Someone has a schematic for a SS HV transformerless reverb

[Kagliostro]

I'm looking for the schematic of a SS High Voltage (may be Mosfet) Transformerless Reverb circuit to be put in tube amps

Someone has seen something like that ?

Thanks

Pedal in the effects loop?

[TUBEDUDE]

If it's to be solid state, why high voltage?

[Kagliostro]

I forgot to say

the use is to mod existing Tube Amp, no external pedal

If it's transformerless then the tank input is low impedance and I seriously doubt it requires high voltage drive signal.


Did you think this topic over thoroughly before posting?

I understand near nothing about SS circuits

so I've asked

here is an easy idea:

buy a holy grail nano - gut it - place it between the input jack and V1 - power it off 9V (either from the heater supply or a small PSU in the amp)

and you're done! $99 solution

That is one solution, thanks for the suggestion, but there are more

You would want a high impedance input tank, Ampeg and a few others used them, Acutronics 800 ohm or 1600, can't remember which though. Using a LND150 for recovery, maybe one and an IRF820 in source follower for drive. I had a circuit someone in South Korea did that looked promising but lost it when my computer crashed. Have not been able to find it since, was a blog, no time yet to come up with my own circuit. It can be done, other than that I can not be much of help.
