Official Fisher SA-100 schematic needed

[inai]

I'm restoring my SA-100, and my power supply voltages are not matching the Sam's Photofact that is available on the web. This Sam's has several mistakes that have been discussed in previous threads, so I am searching for a copy of the actual Fisher schematic for this amp. (the owner's manual too)

If anyone can help it would really make the job easier.

Exactly what I needed.

This lists voltages as 395, 300, 290. Sam's gives 380, 290, 270.

Thanks!

inai; Fisher listed a variance of +/-15% on voltages due to differences in tubes, caps, resistors used. Also they had an allowable input voltage of 105 to 120, with an ideal of 117V. 117V was the factory input voltage for their test lab. So you can have a variance in the voltages as much as 15% either way. The voltages you are listing for SAMS are lower than the FISHER listing but well within the 15% variance.

It's not specifically stated in the Statesman manual but I've seen it in more manuals than not, ranging from my 1951 Coronet to my 1969 Royal Electra.

Larry,

I agree, but when I'm running high, and Sam's is low, I can get above the 15% tolerance from Sam's, but still be OK on the official Fisher schematic.
