Bikes, baseball and big amps.
I just finished up the final phase of my living room system and am finally enjoying a cool beverage and listening to tunes. Here is what I ended up with.

Thorens TD125 MkII turntable with Microseiki tonearm.
-rebuilt electronics, new capacitors, resistors, improved grounding and shielded audio signal wiring
- refinish Plinth
-installed a new tonearm board made of tigerwood
-new suspenstion springs
-converted from three control buttons to two
-drilled the tonearm board and installed Microseiki MA-77 tone arm
-installed new Microseiki M2100 MM cartridge on HS-1 headshell
-set up cabling with din connector and removable power cord
-installed isolation feet
-polished platter and topped with acrylic mat
-installed Audio Technica tonearm lifter

Sansui 990DB Receiver
-built and installed modern F-2624 Driver circuit board
-reworked F-2617 aux power board for better stability and improved cooling
-replaced 4 BA312 IC's with discrete boards
-replaced every capacitor with audio quality capacitors with higher voltage ratings
-refinished cabinet
-replaced lifted traces with point to point
-pulled cleaned and remounted output transistors with new mica pads and thermal grease
-cleaned all pots and switches
-thoroughly tested Dolby board with oscilloscope - no issues
-1K signal and 8ohm dummy load = 152 WPC before clipping
JBL L-7 Speakers
-recapped with audio grade capacitors w/higher voltage rating.
-added minor amount for new fiberglass to help tighten bass response

Streamer
-WiiM mini Airplay 2
-Neohipo DAC with opamps rolled (OPA1656IDR (3))

Pioneer Elite BDP-95FD Blueray player (for CD's)
-slow to load but worth it for the DTS-HD Master Audio Bitstream
