“No sign of heat on board, in LT area, so probably lightly used.
Recapped all small caps on both boards, Elna caps are absolutely fine. Replace Zener diodes, mounting off the board, and 120R/2.5W droppers, mounting off the board. Replace three-way screw terminals, tired screws.
10k pots were Radiohm, 200k pots were small blue Bourns, with locking solution applied. Opted to replace all pots, as a precaution against possible noise issues, and recalibrate.
Clean PCB thoroughly, and clean off and renew heatsink compound, and brightened up chassis plate, renew earth bonds. Renew signal wiring termination with VDC. Renew signal wiring termination, originally wired pin 3 hot, changed to current pin 2 hot wiring convention. Added new rocker switches, replaited all secondaries. Fuseholders are OK, IECs are OK. 47R assemblies on XLR are OK.
Replaced all M3 screws for caphead, current length with washers. Also, replaced transformer screws, grommets, and larger washers, as per current spec.
Recalibrate, and reset bias, limiters, phase, level.
Check CMRR and opto limiters. Otherwise all behaving well, correct filters and phase alignments. Rebias all channels to run slightly cooler than original, as both were idling at 40 degrees C or so, now down to 29 degrees C approximately.
Appliance test, long soaktest, and retest.

Rebuilt by Barry, upgraded to SL and tweeter upgrade. Originally no acrylic waste in the lower section, this was just pre SL, and experimentation was going on with the bass driver, etc.

"Excellent equipment, wonderful service. I fully recommend Soundgas to anyone in the vintage gear market and I will definitely be a return customer. The gear itself was exactly as advertised and in great condition."
DAVID WRENCH
“I’ve bought a number of items from Soundgas recently, and have been really impressed with their service. It takes the stress out of buying vintage gear to know it’s been properly (and faithfully) serviced or restored. Their after-sales service has also been exemplary. Highly recommended.”
TOM JOHNSTON
Fantastic. From initial contact to the product landing at my door the service provided was outstanding. Safe and secure shipping, quality serviced product.

JOSH LLOYD-WATSON & TOM MCFARLAND - JUNGLE
“Imagine the perfect eBay.... with everything you never knew you wanted… and you can rest assured that your vintage and rare wobbly sound device will turn up on time and in one piece and possibly in even better condition that when it left the workshop. Soundgas - literally amazing."
