Got a bad Citation output or power transformer? Well, don't throw it away!!

If you have a bad Citation II or Citation V output or power transformer it can be rewound. While the number
of rewinders has dropped there are still a few out there. who can rewind it for you.
A replacement is virtually
impossible to find at any price, so a rewind - while it can be costly - is definitely the best solution.
Please
drop me a note if you have any questions.

Some Great Non-Citation Specific Resources...

Interested in using loctal tubes? Here's a quick list of the most useful types for audio, and their octal
equivalents (or near equivalents). Keep in mind you'll need loctal sockets! While they are 8 pin tubes,
the pins are much smaller, and the center key is different. Note: loctal pins need careful cleaning before
installation!

Here's a link to a fantastic site for basics and more advanced tube electronics from Randall Aiken, owner
of Aiken Amplification. Randall's products are musical instrument amps, but his Tech Info pages are terrific
for audio as well! A big thanks to him for the great work:
