Anyone heard the Consonance Cyber 800 amps?

I'm sorry for confusion about other tubes that I said can be used with cyber 800. I personally did not try it. I got this information from one of the papers Steve from "Quest for Sound" gave me when I purchase these amps. If in fact these tubes can not be used with Cyber 800 amps. I will contact Steve & ask him for clarificacion. If those brochures give misleading information they should be removed immediately from his shop display section. Ones again I apologize for any confusion this may cost. Sincerely M.Stark

Please don't worry about it, Mrjstark!

I just don't want anyone ending up with a 4th of July scenario. I have personally tried the JJ KT77, Sovtek 6550, EH KT88, and JJ KT88 in the Cyber 800 tube monoblock amplifiers. None are compatible due to the bias settings. It will be apparent within about 5 to 7 seconds this isn't something that's going to work.

All of the EL34 and 6CA7 I have tried have no issue.

The Cyber 800 uses a cathode bias configuration. While you cannot run the other tube types, it's quite convenient in that there is nothing to adjust.

Stephen is no longer the distributor or a dealer for the line.

Thank you again!

Joe. Thank You for clarification. P.S I did not know that Steve isn't a OPERA dealer any more ( have not talk to him in a while ). I'm very surprise , because Consonance was probably one of his most successful lines. Anyway, thanks again. Sincerely ; M.Stark

"it's quite convenient in that there is nothing to adjust."

Do you mean that there are no bias adjustments for this amp ? I am not familiar with 'a cathode bias configuration.'
Sounds interesting .

Thank you .

Saki70, yes, that is the case. There are no bias adjustments with this amplifier. So long as you make sure you stick with EL34 and 6CA7 output tubes, it's simply plug and play.
