Looking at racking a 4 channel Quad8 mic pre I have.
I'm pretty sure the model is mp404.It has 4 pre's in one module,uses am10's.
Does anyone have suggestions on good output transformers to use?
Also does anyone have pinouts or schematic?May save some time working it out.
THANKS!!!

if this is the little 4 channel board i think it is then it can make a great sounding bank of micpres

see my website here : http://www.proharmonic.com/archive1.htm right down the bottom of the page. Is this what you have ?

naturally the Q8 output transformer makes an ideal mate, but for new transformers the JLM 111DC http://www.jlmaudio.com/JLM111DC_Output_Transformer.htm is very good and allows you to get the 1:2 step ratio

There are AM10 schemos floating around the web, email me if you get stuck. Everything else on that pcb is just power distribution, pad resistors and coupling caps

thanks for the info
yeah thats what I have.
Did a bit of research and appears the cinemag transformers are doing the original quad eight trnsformers again.
What transformers did you use for that 1?

original Q8 transformers
