26/45 SE amp ?

[dobias]

Are there any type 26 driver SE (45, 2A3 or 300B) power amps? The only way I find the 26 used is in a line amp.

One of the posts refers to Gary Pimm's 26 driven parafeed 45 amp, but the link is broken......

Hi!

I built a 26 / 35 amp, see links below. Actually the driver can be configured for either 26 or 10Y type tubes. Output is switchable between 45 and 2A3

My main amp is a 27 driving a 71A, direct coupled. Sound is probably very similar to a 26 / 45 amp, which is to say magnificent! So I say go for it.

boywonder.
You not only help to get me out of trouble, you help to get me into trouble as well.
The information you've listed is over a hundred pages of serious reading. If the participants could only come to a conclusion as to what is best, I wouldn't have so many decisions to make.
I see you have your own plans to work on.
Thanks to everyone for the inputs.
Frank

Heck I'd love to see the schematic on the 27/45

There are many talented people on this forum maybe someone will draw up something for the 26/45 quest.

27 is a great tube and matches the 71A well! 26 is another league however and will sound even better but requires much more care due to the filament supply needs.

For a 45 a 27 or 26 will not provide enough gain to reach the usual sensitivities. Either a preamp with enough gain is required or a input transformer with step up.

Heck I'd love to see the schematic on the 27/45

Check out the schematic of my 46 amp:

Can be adapted for 45 as output tube. A 27 would fit in nicely, but note my remarks about gain above.
