Hi all,
For some week, I'm interested in some investigations in Tube operational amplifier :..I've found some nice schemo (F.Forssel tube amp,Borbely and the old K2-V),nice read about the subject in the Meta.My holy Goal may seems as..
TOA:
-Design on 2 tubes ecc86 dual triodes (this one was used in car radio set).
-One for Diff.input pair.
-V+ and V- low voltage (+-24v to +- 48v).
-Pin as 2520.
TOA 2:
-Design on 2 tubes as 6111 or 6021 dual triodes.
-One for....
-V+ and V- high voltage (+- 100v to 150v).
-Pin as 2520.
Mother board:
-Pad.
-48V.
-Phase.
-may be Line in.
-Tx In (1:10 Transformer for some gain).
-Line driver as Srpp output stage or XX oneTransformer out
So, I wanted to know if someone as an idea for the electronical design for the stage after the Diff.Input tube :,I didn't have tube simulator for design it ,so I still with my pen ;D and going to build one by trivial and make an Holy and beautiful burn on my bench
..Best regards,Bruno.
