I think this counts as Past Masters if it’s older than me...
Anyway, I picked up this lovely sounding STA15 the other week. It’s been to David Coe/AD Audio within the last couple of years for new caps, speaker binding posts and valve runners and sockets. The transformer cage is showing it’s age, but a new one should be on its way from Will at Radford Revival. The main casework is a little beat up, but that’s a much bigger job!
Sounds great already. I was worried my speakers wouldn’t be sensitive enough, but no issues there in my small room.
I wanted to ask about others’ valve choices with these?
This is currently fitted with the following:
Mullard/Zaerix GZ34
2 x Telefunken ECF82
2 x Telefunken EF86
4 x Svetlana EL34s
Which valves (output/signal/splitter/rectifier) tends to have the greatest impact on SQ?
I’ve been looking around at EL34s and may get a set of the Winged ‘C’ valves as I think it currently has the reissues fitted. These seem to be a good balance between cost and reputation.
What about KT77s? I’ve seen someone singing the praises of 6CA7 Shuguang Treasures which I think may also work?
Grateful for anyone’s advice. I’m in no rush as it already sounds good to my ears, just interested in having a play.
