Quick project: Why did the fuse blow in my vintage Dynaco ST-70?
(If you’re not familiar with Dynaco, you should be: Dynaco wikipedia article)
Here’s what one of my rebuilt Dynaco ST-70’s looks like:
Tube amps have, well, tubes. And they wear out, eventually. This amps rectifier tube died and caused an over-current condition, presto fuse blows. Checked the other tubes and the bias current, all looks good now.
And now, on to the next thing!
Here’s my retro and obsolete audio media players and decoders rack.
From top to bottom:
- On top, the classic Technics 1210 MK5 turntable. Modified to play 78’s as well as microgroove moderns
- Furman Power conditioner – the newest thing here
- Pioneer 707 7″ reel to reel deck
- Tascam Patch bay
- dbx type 1 and 2 decoders. The lower one also handles dbx encoded discs
- NIKKO BETA 30 preamp
- Panasonic SV-3700 pro studio DAT deck
- TEAC R400x cassette deck – one of the few decks that has Dolby B, C *and* dbx NR
- Pioneer DV-563A multiregion DVD player, plays SACD discs
- SAE 5000A pop and tick remover & flat phono preamp
- dbx 3BX dynamic range expander
- dbx 120 subharmonic synthesizer
