Schematic for Ampeg SVT Classic CL-W

[soundrepairs]

Hi,

Am looking for a schematic for this - and so far have only been able to find the 1969/1970 versions, but what I need is the newer, 90's, version.

Would be great if anyone can help, cheers.

Strangely enough we've got another one on the bench at the moment... the screen resistors are 220R and grid resistors are 47K... it's the first thing I check when one of these comes in... quality Vietnamese goods... NOT!

There was a 2001 service bulletin changing the screen resistors from 22 ohms to 220 ohms.

Hi Valvehead,

Here is the missing schematic.

BTW, both all previous and attached here
schematics correspond to the SVT Classic CL model.

What is the difference between SVT Classic CL and
SVT Classic CL-W models?
