Default A friend has one Sherwood..but he has no schematic


we have tried to reverse engineer that one..and i found the circuit very interesting till i turn tired...it is a hell hard job only using pictures to do that...but this one is almost ready.

Differential input, a nice VAS with a 33pf miller, quasi complementary, DC coupled... very well made... also has an E/I limiter into the output (small transistors you see)

Send me schematics please.... i want to build one to listen that lovely brand from my youth

Yes...i found many adresses having 14 to 30 USD manuals.... i cannot afford boys... send me for free, please.

regards,

Carlos

Default Here you have the Sherwood Dynaquad Stereo amplifier SEL400


I have made a small image to our forum.... not very good i know...if you want the bigger one, a complete one, with pré amplifier, supply, controls and all stuff, then write to me:

panzertoo@yahoo.com

The pdf i have is too much big to our forum limits.

regards,

Carlos

Default C'mon boys...help old uncle Charlie!


I know that some guys thinks this way:

- "I have paid when i had the need of schematics....if i have paid...he can pay too!"

It is all rigth.... reasonable logics...but..inside your pocket there are much more money than brazilians have...you earn 20 times more than we earn (real value..capacity to pay and buy gods)... when you pay 10 bucks to an schematic, you're paying the Macdonalds hamburger and potato chips...we can eat good meat for a weak with this money...values are different...standards of life are different.

So..be nice, kind and cooperative man...help old uncle.

Watch the hell hard work i am doing... a schematic would be helpfull.

regards,

Carlos

Hello Carlos

I did look for your Sherwood amp but I did not found any free schematics and it is not in my amps books.

Old Sherwood amps free schematics are quite hard to find.

Bye
