any perspective on these? http://www.sophiaelectric.com/pages/se/274b.htm
BTW, when swapping tubes, how long do you wait for them to cool down before you take one out and replace it with another? Cool to touch? Just wondering....
I vaguely recall Skylab over here having experimented with really expensive rectifiers like the 274b.
The conclusion was that it would be better to stick to 5Y3 rectifers coz the CSP2+ was designed around it.
As for swapping tubes, there was some discussion before on the Decware forums.
Steve actually confirmed that you can yank out the hot tube whilst the CSP2+ is still running.
I'm the more cautious type and would prefer to wait about 10 mins.
