ARCDB - D-90


Schematic for the D-90. B is a variation with different tubes on the front end, and regulation. Hopefully this will give you what you need.

audio research D90B

thanks, my doubt is that the amplifier that I have no voltage regulator as the D90 carries a power source 6550, the model I have is D90B, now is the same?

thanks very much

regards
