McIntosh MC2205 Restoration - this one was a labor of love; came in with a smashed faceplate, bent gain pots, rusted out lamp bezels and chassis screws, and a sad looking wood case with a completely broken and missing cross brace 😒 After new glass + many hours of cosmetic and electrical work, it looks like it should be in a museum 😀

Kenwood TK-40: fun little early solid state receiver. Shipped to me by the original owners family, and by the looks of it had never been serviced. Wasn't planning on fully recapping this unit, but leaky caps were everywhere and causing issues in every section. After restoration it sounds fantastic, very tube like. Cleaned up nicely if I don't say so myself 😎

Harman Kardon TA600 - somewhat of a rare bird. Completely rebuilt this one: fully recapped, replaced original Darlington output devices with new TIP Darlingtons, replaced all problematic transistors, cleaned controls + tuning cap, realigned tuner, and refinished case. Looks beautiful and sounds even better!

⭐️⭐️A sight to behold, the Technics RS-1700 Auto Reverse!⭐️⭐️

This one was not recording in the R channel, had a nasty squeal during FF/REW, and reels that wouldn't stop spinning after the tape ran out: both relay's were found to have corroded contacts, due to lack of modern replacement, contacts were cleaned. Then it just needed a drop of oil on the timing belt pulley, an adjustment of tension arm micro-switches, and a good tape path cleaning. Sounds excellent now 👍👍👍
