Hallo aus den USA! Dies ist meine vierte Verstärker zu bauen. Ich begann mit einem Fender Champ. Dann ein Marshall (Metro) Superlead, JCM800, und nun dies. Ich bin mit den Schaltplan aus C3-Amps, als auch die "PCB", Chassis und O'Netics Transformatoren.
Filterkondensatoren sind Panisonic.
Coupleing und Bypass-Kondensatoren sind Sprague 716p.
Widerstände sind Dale / Vishay.
Potentiometer sind Clarostat.
Genießen Sie!

Made some progress today. Preamp board is mostly finished. I just have a few small bugs to work out like the wrong wattage on two resistors in the power section and still need to install some jumpers. Also missing a ceramic disk cap.

Installed most of the rest of the chassis stuff (except for the pots, still have to cut the shafts to length):

(http://fc00.deviantart.net/fs71/f/2014/179/6/4/preamp_board_3_by_haftelm-d7oal40.jpg)
One issue I've run into is this corner of the PCB board. The stand-off mounting hole in the corner of the board is too close to one of the F&T caps. So I can't get the nut on. I'm trying to figure out a way around this. There is another hole in the PCB to mount the cap a little farther away from the stand-off mount. But that would require me unsoldering the cap, cleaning up the solder/flux, rebending the cap leads and re-soldering.

Removed the powder coat around the switches and pots for chassis-ground. Was a lot harder than I thought. Wound up using a Dremel. White powder EVERYWHERE. Should have worn a mask :)

Ok, on to the preamp heaters. Usually wiring up heaters is my least favorite part of building an amp. It's a pain in the ass. The normal way, I'll just throw some wire into the chuck of a drill and twist away. Then cut lengths as needed and bend and wire and weave it all together. Easier than doing it by hand, but still torture.
I was actually looking forward to doing the heaters on this build, though. Just some straight wire and you're done! Love it :)
If you've ever wondered how to get straight bus wire, this is how I decided to do it. I used an armorer's block that I use to strip down my 1911 and drilled an 18-20 AWG hole thru it. Then I put one end of the wire in a drill and "extrude" it through the block while the drill rotates. I move the block back and forth slowly and carefully until the wire is as straight as I can get it and/or until I get super bored. Then I'll roll the wire under a wine bottle on a flat counter a bit for good measure. Seems to do the trick. Just takes a while.

Sort of at an impasse for the time being. Can't do much else until I cut the pot shafts and replace the power tube sockets. But I got most of the switch stack done (at least all I can for the moment).

Thanks, guys! I hope it turns out as well as a real SLO :)

Hi,
I think so!

Hmm, I don't know anybody who is able to get original DeYoung transformers for their DIY build. They don't sell them to the public. I'm using O'Netics "Hi-Def." But I believe Soldano actually uses this transformer set in their other amps (Avenger, Hot Rod, etc.), just not the SLO. So it's close enough for me! :)

Been busy with work and life and such lately. But managed to make a little more progress: Pot shafts are cut to correct size now, started on wiring 'em up. And got new power tube sockets.

More progress today. Just the two shielded coax cables going from the gain pots to V1 and V2. They took a while to do because of how perfect you have to strip them, get the lengths correct, and splice in a resistor on V2. But having the coax stripper really helps. I had to adjust the blade depth a few times to get it right. Out of the box it was cutting through the shield. Here's what it looks like all stripped and tinned. Nice and perfect! :D You know it's tinned well when you can still see the braid. Too much solder and each wire in the braid would be covered.
(http://fc03.deviantart.net/fs71/f/2014/191/3/8/photo_1_by_haftelm-d7q3n53.jpg)
I had a heart attack when I went to check continuity on the coax. I was getting a short between the shield and the conductor. And I was like FUCK! I'm gonna have to redo this all again! But then I realized the gain pots were on zero, thus shunting to ground. I was super relieved. :)

Heaters are finally done. Phew! Took longer than doing it the usual way with twisted pairs. But I think overall it was easier. Sure as hell looks better too.
I have some parts on the way for the elevated heater mod too. Just a cap and two resistors for referencing to the choke on pin 6 of the power tubes. Then I can do the faux center tap and finish the rest of the power sockets. Then put in the transformers and start on the power section.

Most of the power section is done. Once the preamp is wired up I can finalize the remaining connections on the power board. It's not as tidy as I really want. But there are a lot of wire runs in the SLO. Good thing they're all covered by the power PCB :) And I spliced in the lead from the OT to the HT Fuse.

Damn, power tube sockets took a long time. But they're finally done. Just need to add some heat shrink to the grid stoppers. Next steps will be the loop jacks, impedance selector, and then I can move on to the preamp board wiring and I'll be done.

Output jacks, impedance selector, and FX loop return wired up. I'm not going to do the slave out. I never use it. And I can always add it later if I want to run wet/dry or something.

So close!
Had to figure out a way to hold the preamp board up off the table, while at the same time keeping the lead I was soldering from falling out since they're installed from the top of the board. That's where these Helping Hands come in handy. Was pretty easy. :)

Awesome.
The slave out is useful if you want to record thru Torpedo's software. Then you can skip the power amp simulation. Just hook the amp to a load, Mike.
-
That's going to be an awesome amp, great build quality.
Is there a particular reason why you used the "purple wiring code"? (just kidding ;D)
Cheers Stephan

Purple sounds better!

Got the AC lines, Depth control, loop, and channel switch all wired up. Board is now locked in.

Was out doing real-world stuff for the majority of the day. So did a couple of the small things left to do here and there: Power Board to Preamp Board jumpers for Bias, B+, and Ground; signal coax to V3/7 (not shown); and remote bias control.

Powered up. No smoke, no sparks. Everything seems good. :) I think all the voltages check out for the most part. Some are a bit higher, some lower. Plate voltage is crazy high... 520 volts. Damn. Highest I've seen in any amp.

Hi!
Really nice job!! Looks amazing :topjob:
Waiting for the final test: walls shaking test in the house ;D
Is the voltage of the PI V5-pin 6 a typing mistake? Should probably be 257.9 instead of 357.9V, right?

Laurent

It might be a mistake. I will check again tomorrow. Good catch!
Biased up the power tubes and everything seems good, though. Haven't had a chance to crank the amp yet, though. Will do that tomorrow as well. :D

Here are some clips. I'm still tweaking this thing here and there, trying to find the best combination of speakers and tubes. These clips aren't to showcase my playing, just the tone of the amp. Recorded with my laptop's webcam, so not the best quality obviously. But that's all I have.

Hi,

I like the LesPaul silverburst, looks like an old one from ´79 or is it one of the RI Customs?

That one is an '84. I have a '79 too. Different necks on each. One is mahogany, the other maple.

I keep coming back to this thread whenever I want to see how clean a build can be. Pure art, great motivation! Probably will never build one (scared of high voltages, stompboxes are fine), but if you want to sell yours, let me know!!!
