Default TSE power transformer & choke choice.

Hello chaps,

I'm gearing up to start buying bits for an upcoming TSE build. Would someone kindly see if these two components are compatible please.

I intend to only use 300b tubes.

Its to operate on UK mains voltage - 240v.

Edcor xpwr131 power trans.

Edcor cxc125-10h-200ma choke

Cheers, all help is appreciated!

Similar to what I have chosen:

Edcor 131

James Audio 10H 200MA choke

Choke arrived an hour ago and Edcor will be a while but I have checked and these are fine components to use (outputs, etc) so I think you will be good to go, mudchute.

Mudchute: Those components will work fine for a 300B TSE.

Yes I like the look of the James kit, I'll probably get swayed by it.

Whilst on the subject of James transformers is the js-6123hs opt a wise choice for a 300b se?

I have an sse with big cxse edcors and I like the big sound and huge bass so i'd like the same but... Better!

I have the JS6123 pair though am still in the build stage so cannot comment on their performance.

I know boywonder likes his a lot.

They are certainly suitable for the build according to the advice I have been given here.

I think it's a great choice. The multiple output taps also allow running 45's, 2A3's etc.

I'm more tempted now. Have you compared the James transformers to the edcors?

These are to be used with my current alpair 7.3 mar-ken or future set of alpair 10.3 mar-ken speakers. The 7's are about 86db efficient and the 10.3's 90db efficient.

I have Edcor output transformers in my EL34/6GK5 Music Machine (Poindexter design) and I like that amp very much as well. It's triode wired PP about 14W.

I have a pair of Hashimoto transformers to use in the MM when the mood strikes to do a rebuild, but I'm pretty content right now.

So, the short answer is no, I have not compared SE output transformers in the TSE.
