I know this site is for Kustom equipment, but I just got a hold of a PhotoFact Servicer that contains the complete schematic and parts list for a Silvertone model 1465 amp head. Not to worry, there are no copy right issues. I had and now have again one of these vintage heads from the mid 60's and figure there might be one or two of you out there that might have one as well.
$5.00 if you want a printed copy or send your email address and I'll send you the download.
As more manuals start surfacing, I will let everyone know about them.
