Ampeg SVT 450 sound test after fix

This Ampeg bass amplifier came in with cutting off sound randomly.
After a deep inspection we found a previous fix attempt on the gain pot with its connections without any insulations, cold solder joints on allmost all pots and in/out jacks and a ton of dust.
We gave the amp a deep clean, replace the gain pot with insulated wires, replace all suspicious cold solder joint with a fresh leaded one on all pots and ins/outs jacks.
The amp is ready to rock again!
