No offense,but feel free to wright in German if you wish. I understand it perfectly well,it´s just way faster to me to wright in English as i was brought up with it.
Hope none of you guys mind that.

Ah, gut! Es gebietet die Höflichkeit auf einem deutschsprachigen Forum, dass zumindest die, die es gut können, beim Deutsch bleiben.

Ich bin auch quasi bilingual, aber mein geschriebenes Deutsch ist etwas besser als mein Englisch, während ich in der Küche (mein Hauptjob dieser Tage) und bei Audio/Recording (mein früherer Job) und nun auch Röhrentechnik klaffende Lücken im deutschen Vokabular habe und daher andauernd dieses seltsame Denglish schreibe...  :-[

Racing:
*LOL*
Nah..your english is as good as they come. Take my word for it!
Agreed though that it might be an idea that we all stick to what we know best... ;D My biggest concern,to be honest,is that to this day not all understand/appreciate english. Well..can´t win ´em all i guess.
TBH my english limps a bit too these days having lived in Sweden for the better part of 30yrs.. ::)  Anyways.

Yeah.



I kept my solution real simple. About as simple as it gets and it indeed makes a Twen open up. That said,please please please those of you doing so stop selling the old Dynacords and what not cheap...read on...

Speaking of which. I to this day don´t get why you guys don´t dwell on your domestic production of tube amps more then you do. From a pure tech point of view the German made tube amps outshine most of what was ever produced in Britain and the US.
What the German made amps of the time lacked was...modern day n era sound,but see sound can always be altered by us simply resetting topology for the tubes present.

Having to reengineer e pisspoor design on the other hand though,as for the amp as a whole,is another matter. Just take a look at most generic made British amps of the time,they´re a damn joke TBH..built with whatever happend to be present in the part bin.

My personal preference with German made amps is indeed Klemt and in turn actually Austrovox (Austrian,i know..but they´re friggin deadringers designwise for the Klemts).
The boys of Klemt,to this day as far as i´m concerned,produced some of the finest guitar and bass tube amps ever conceived. As one takes a step back and REALLY ponder and regard what´s on the bench,why parts have ended up where they have and why the chassis is put together as it is and so forth...them boys knew what the F they were doing.
All said and done if you hand an old BS-40 what it can handle they surpass 50 watts with ease. Remember..distorted signal  ;D They do so at the weight of approx 10kg. Compare that to a 50w JMP....cheers!



So yeah. I own a bunch of BS-40´s as well as Showstars,Mustangs..down to the Winston GA-200 (a couple) and the  PA-200. All great amps. All amps that were truly DESIGNED.
Just take a look at the presence control of a Showstar...genius. Just plain friggin genius.

Of course there´s a couple of ET-100´s around. The early ones,with the gold baffle fabric,is the ones to get IMO as their frame is out of solid pine which makes them light. Put on a scale they tend to tip in at around 11kg-12kg.
What i do is that i remove one of the stock P30/37´s and replace that with an Eminence Cannabis Rex. The CR then provides the volume and the P30/37 the grit. A REAL good match if you ask me.
Then...check what the CR´s run..they´re friggin cheap.

Racing:
Speaking of EL-84s vs 6V6s...
Have built a crapload of them by now,as you  seemed to be aware.

Hoooooowever... >:D im right now knee deep in a pair of old Swedish made Sinus amps. Sinus model F12A´s. I´ve basically wiped them clean,the one is of -51 vintage and the other a -52 vintage,and will basically just reuse the powertransformers,their chassis and chokes.
Ok?
So?
Well. Idea of mine is to put together two real similar amps. Just one sporting a pair of EL-84´s and the other 6V6´s. Mainly to put them together as "cousins".
Further i´m going to keep it KISS. Keep It Simple Stupid.

As of lately though..i´ve come to grow fond of the 6V6 format. Sound difference them between isn´t a landslide exactly but it´s there..and at the time at least the 6V6 comes out ontop to my taste.

Further. Just finished a Swedish "mystery" amp. An old mid -40´s product with sides out of solid mahogony. Uses real old 6L6G´s for power. Really neat amp. Well built.

Morning,

ich glaube im Moment, dass hier in Deutschland alle Verkäufer von Dyna Twens, Jazzes, Rexes, DA16s etc. glauben, sie hätten blattvergoldete Vintage-Amps im Angebot! Nicht-restaurierte, teilweise verbastelte (FX-Loop...OMG!!) für 280-300 €, mit erfolgtem Cap Job kaum mehr!!! Wenn man bedenkt, dass eine Restauration mit guten Bauteilen, Röhren und Speaker locker 200 € kosten kann, man aber maximal 300 € wieder dafür bekommt, stimmt da was nicht. Ich denke auch, dass deutsche Amps der 60er im Wert steigen werden, nicht so wie solche aus US oder UK, aber dennoch. Allerdings muss es doch einen substantiellen preislichen Unterschied geben zwischen einem "Dachbodenfund" und einem restaurierten Amp, der Teile und Arbeit reflektiert. Ist ja bei alten Fender-Amps nicht anders.

Ich kann Dir sagen warum: mit der rühmlichen Ausnahme von Autos und Bier haben die Deutschen - speziell die jüngeren Generationen - immer ihre eigenen Errungenschaften und Produkte verschmäht. Nicht mal unsere eigene Musik haben wir wirklich je geliebt. Seit den 50ern versuchen wir amerikanischer zu sein als die Amerikaner (was nie funktioniert hat, weil wir nicht 'easy' genug, aber auch nicht naiv genug sind), unsere Radiosender spielen zu 90% US-Musik, das TV wird amerikanisch dominiert. In den 60ern war unsere erste Gitarre eine deutsche (in den 70ern eine japanische), aber die erste richtige Gitarre musste eine amerikanische sein. In Deutschland wurden Echolette- und Dynacord-Amps nur so lange gespielt, bis die transatlantischen Zollschranken teilweise stark verringert wurden; gegen Ende der 60er überschwemmten US-Produkte den europäischen Markt und auch Otto Normalmusiker konnte nun Fender-Amps und -Gitarren erwerben. Das kann man sich heute kaum noch vorstellen.

Überhaupt begannen Jim Marshall, Thomas Jennings und auch die Jungs von Dynacord und Echolette ja nur mit dem Bau vom Amps, weil die Zollbeschränkungen zwischen dem europäischen und dem US-Markt einen bezahlbaren Import verhinderten. Ebenso konnten nur die größten US-Studios, die den internationalen Plattenfirmen gehörten, überhaupt ein Neumann U47 ihr Eigen nennen. Daher der ganze andere Klang vieler amerikanischer Aufnahmen aus den 40ern, 50ern und frühen 60ern im Vergleich zu europäischen Produktionen.

Ich habe den BS40 ja immer für einen JTM45/Bassman-Hybriden gehalten. Da ich ein großer Fan von Brian Setzers Gitarrenton bin, habe ich in meine ET-100 kürzlich zwei alte Vintage 30, noch aus Ipswich (nicht China), geschraubt, den BS40 eingeschaltet und in die Saiten gehauen. Nach dem ersten Akkord musste ich meine Unterhose wechseln - ich hatte vergessen WIE LAUT eine solche Anlage mit sehr effizienten Speakern sein kann!!!! Ich hatte regelrecht Angst vor dem Amp. Also habe ich auf die (verdammt gut klingenden Vintage 30 - bin ja sonst auch kein Fan davon!) verzichtet. Jetzt habe ich zwei Jensen C12Q drin, ein ganz anderer Ton, aber es klingt sehr nach Bassman.

I hear ya.
In that case they´re cheaper up here. An old Dyna Hall-Jazz will set you back like 100 Euros. Ditto for most Dynacord made amps really...
The Klemt are normally somewhat more expensive,with emphasis on somewhat.
I´m 100% with you in that there needs to be a differ between what is an untouched relic and something that´s seen severe service and is good to go. No argument.

Hm. I guess what you to an extent is saying is "o tempera o mores".? Might very well be. Up here i´m doing my damndest to make guitarist as a whole understand and appreciate that sound per se can always be reset. ALWAYS. Sound is mainly a function of topology and that´s it,and i for one have grown to boredom in that an amp HAS to be a rectangular thing in black tolex. It has come to the point where the mere proposition makes me want to barf.
Enough of that crap already! Bring in some good old fashioned hotroding..attitude..humour. We do this music thingy,play that is,because it´s fun for the love of god! Then WHY on gods forsaken earth do we need to be stiff upper lip as far as our amps? A guitar can look basically any way and form these days but...amps.? God forbid that someone puts out something that isn´t rectangular and covered in black tolex!

The US...*LOL*. Yeah. An expression a German friend of mine handed me..."amerikanisches ambassade"= McDonalds. Nah. I hear you,to the letter.
Up here though,to be honest.. "The Swedish music wonder". That much is true. We´ve always been at the forefront with that,and to a degree are to this day.
Just take modern day n era metal. Scandinavian such is known around the world. Town where i LIVE is even known for it..."the Gothenburg sound".
Pitty that your younger generation obviously don´t take pride in German music history. Real pitty,because as always there´s guaranteed to be lots to be learned.

The BS-40 (and it´s syblings).
Yes yes yes and yes. In stock form though i find them rather "German" to the sound. Rather harsh,shrill and brilliant. That can be handled real easy though.
Word of advice,again  ;),if you want to widen that amp in a rather immense way...install a PPIMV pot. Makes the one amp be able to run from squeeky clean into...as you´ve touched upon...Marshall-eresk distortion.
I can´t for the life of me understand why not most "old school" amps are so equipped. It´s just beyond me.
