Dynaco Durability - a $15 ST-70

Some guys have all the luck. This YouTuber documents a thrift-shop find which is drool-worthy. This unit's survival is undoubtedly due solely to the bomb-proof design and build of the early ST-70. Hopefully, he eventually did the right thing - a Latino board. Watch 'em and weep.

It is unclear from the evidence, but one supposes that due to the non-working right channel (the 7199 on the board is not lit up, but those original EL-34s are bright) that this guy may have run this amp with no load on the right channel extensively. And, once fixed, there was no damage. What an amp.

My ST-70 I inherited from a dear old DJ friend who passed away and who was the undisputed number one source of knowledge on old records, who played on them, where they were recorded, etc. etc. I turned him on to Dynas many years ago and he picked his up at a thrift store with the cage still clearly marked "$4.95" in Sharpie. I'm not sure if he talked them down or not....
