This is probably Sonys best VFET integrated amp, the very rare TA-F7. A phenomenal piece from the glory days of Japanese audio design. The amp has been serviced, mostly to protect the amp and especially the VFETs against failure. - The output cascode BJTs (common failure point on these) were replaced with modern D44H11/D45H11. - The fusible resistors were replaced with superior modern replacements. The originals are known to drift. - High quality Bergquist silicone thermal pads for the VFETs. - General maintenance/servicing—bias adjustments etc. One thing we overlooked was the VU meter bulbs—they need to be replaced. At some point, you could also fully recap it—my tech considers full recaps very much optional, so he didnt do it. Some caps were replaced in the power supply though. Cosmetic condition is very good with only a few small marks. I think its a nice example overall. Its a 100V unit so youll need a stepdown transformer. Local pickup or Ill ship it safely packed with lot of protection. I can ship it internationally—message me for a shipping quote.
