Upgrades for the TU 8300R
Hello Victor
I bought the 879S a couple years back and I seemed to recall finding several sources of information on upgrades. Amongst them were capacitor and volume pot upgrades. I have purchased the TU-8300R and was wondering if I could buy the DX parts from you? Also, are there any posts here showing a build?
Thx
Dave
