Hi,
I´ve got one for the 8100.
Don´t know if it´s the same.
If you wanna have it drop me a mail and I`ll send it over (420kB).

Hi I have got the Valvestate 65 schematics: they should be similar. Send me an Email if you want them...

An Hint: post this on http://www.firebottle.com/fireforum/...fg=ga&enter=go
Maybe there you'll find them...

thank you guys.
I also have VS65 and 8080,8100 but I need VS100R's schem.
Someone has done some mods in it and I'd like to repair it.
The problem with other schems is that the component numbers are not the same.
For example a pot named VR2 isn't the same with the VR2 on VS65 schem.
And I think that there are some differences in the preamp stage of VS65 and VS100.

Send me an email with "VS100R Schematic" in the subject line.

My email is tmenzo

then the symbol for "at"

then msn dot com

Those VS series circuits are related but not the same.

Thank you Enzo,
Seems that is what I needed!!
The only difference is that on my PCB there's a different code number...V100-60-00 for the preamp unit instead of V100-60-02...I don't have the other PCBs in front of me.
But the circuit looks exactly the same.
I don't know why but the previous owner is...

!!!
IC6 is missing!!!!!!!!!!!
What kind of IC is this? M5201?????
It isn't a normal op-amp.It's sth like a mixer op-amp!?

Any good marshall dealer in Europe?So I can order some parts?
I need three pots and this strange op-amp.
As I can see from the other op-amps on the PCB,it's a mitsubishi 5201A.
I ask my local surplus store for this but...nothing.He told me that I can order it only from a Marshall dealer.

I would contact Marshall and ask them who distributes parts for them in Europe. I always get my 5201s from Marshall here. If I recall well, it is an analog switch IC, used to route signals
