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!

Whilst on the subject of James transformers is the js-6123hs opt a wise choice for a 300b se?
I think it's a great choice. The multiple output taps also allow running 45's, 2A3's etc.
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.

Can anyone clarify please if this output transformer will work in a 300b SE.

Sure, it will work fine, and would be a great choice. Comparing it to the 6123 transformer, it has 10ma more current capacity, it's physically larger and heavier so probably more inductance (note the difference in FR), and it has a UL tap (denoted by the "S" in the P/N-useless when using a triode like a 300B) for running UL mode with pentodes like EL34.
The 6133 has 3.5K primary impedance, so not as flexible as the 6123 with 2.5/3.5/5K primary impedance.
Ah thats good news then. I've unknowingly listended to the 6123 ina 300b amp before and it left an impression. My only complaint was a lack of LF response which I hope the 6133 would rectify. I'm hopin gthe 6133 is the answer I'm looking for.
I was entertaing the 5k primary option so it'll be good to hear you views on the 3.5k/5k switch if at all possible boywonder.

I really don't have an opinion on the 3.5K/5K choice.
My 300B version TSE is running 6123 transformers on the 5K tap. I haven't tried the 3.5K taps. Running a higher primary impedance typically yields slightly less power and distortion than lower primary impedances.
If you want to wring every last drop of power out, use the lower impedance taps, for a little less distortion (and power) run the higher impedance taps.
