Same Tex that visited me with Raven?
Sorry, but we no longer have any amplifier parts, other than an occasional knob or something at might appear in our eBay outlet.
However, all of the electronic parts are readily available and even those no longer produced (i.e. some semiconductors) have easily cross-referenced replacements off the shelf that are in many cases better than the originals.
PC boards and pots are about the only thing not readily available, but these are always rebuild-able or otherwise able to be recreated.
Presumably you are also aware that the schematic is available online here: http://www.rickenbacker.com/pdfs/19525.pdf
