Hello guys,
Just completed the TSE, works really well, but unfortunately I am a little disappointed in the EDCOR PT (XPWR131-240) - there is quite a noticeable mechanical buzz...Not loud but noticeable. I have tried tightening the screws but the buzz is still there ;-(
Has anyone had this issue?
Appreciate any feedback,
Cheers,
-Victor

This is where I bought mine from. It had to go through some diy modification though. http://www.diyaudio.com/forums/tubelab/148378-tubelab-se-alternate-power-transformer.html

Thanks guys,
Evenharmonics -appreciate the info ;-)
Boywonder - are you using 300b or 45's in your TSE?
Have a feeling I am overloading the PT. With 300b biased at 65 ma it looks like I am drawing close to 200 ma from the secondary (XPWR131 is rated at 175 ma). The PT is getting quite warm after a couple of hours. Have sent a question to Edcor.

I have two TSE's, one running 300B's at 60ma and the other running 45's. Both with the XPWR-131-120 power transformer.
Thanks Boywonder,
Can I ask you how hot your XPWR131 gets in the 300b TSE?
I can't remember the exact theory but recall vaguely that the same core will be closer to saturation at lower frequency (my 50Hz vs your 60 Hz - that is 20% difference!) - perhaps that is why I am getting this slight noise and heat? Thanks for your help.
