Here's a Sansui TR-707A someone gave me to repair. Put the top back on and it's still sitting like this wrapped in a plastic bag.

Not exactly nude. It looks like it's wearing a sweater!

My Pioneer SX-1080 with reduced heat on Power Supply Assembly.
Very little room for bigger heatsinks so I decided to move Transistors Q1, Q5 and Q6 to a better place.
These are known to get very hot together with diodes and resistors which also get quite hot in this area,
Heat on the transistors was around 60 to 70 deg C and are know down to around 40 deg C.
Big improvement inspired by similar action on a SX-1980 i read here on one of the forums.

APT Holman pre amplifier that just left the bench. Replaced 41 capacitors, 23 2SC1345 transistors, 12 opAmps (with sockets), 1 relay, and installed headers and ribbon cables to allow disassembly.
