Titel: LNDverb without OT ?
Beitrag von: Pandjesbaas am Jul 15, 2022, 10:15
Hello good people,

Would it be possible to use the LNDverb-kit to drive an Accutronics/Belton digital reverb WITHOUT the use of an OT?

Hi,

Please do not do this.

Thank you for your comment...
But why should it not work?
If I replace the OT with an appropriate resistor and use a coupling cap, shouldn't it do the trick?
Or am I missing out something?

If you do that, you will have a high voltage connection to your reverb tank.

There are other ways to handle this, please do seek information on the valve wizard website

The high voltage will be separated by a coupling cap...

Maybe there is a misunderstanding

you do/must not have to use the lnd for driving a digital reverb. It is not like a reverb spring. The digital reverb unit is made for working in low voltage area and does not need a driver like a tube or a hi voltage FET together with an OT.  But you can use this unit like an effects unit.

It has to be matched adeqautely regarding the level and impedance and a coupling capacitor for DC  blocking, that is all. For that have a look at effect insert schematics. You can handle it like an external effects unit.

Regards
Herbie

Is that so? Please enlighten me, oh sun of knowledge...
