I have not read much on power transformers and which are your favorites. I am looking for highest quality and performance for my 2A3 amplifier that currently uses a Hammond 272DX. I want to "upgrade" if possible.The PT that I currently have, Hammond 272DX, has had two of the lead wire break away from the core wires. So, I am looking for something of higher build quality / reliability. Also, not sure if PTs make a sonic difference or not, but if so, which PTs in your experience are considered sonically superior. I know this is subjective, but at least its a starting point for me to investigate.
Please give us your recommendations.
Thanks, Pat

Banpuku - I used to buy Hammond power trannys but found they are A) quite expensive B)Made in Canada C) have 115v primaries. Which need to be compensated for with modern 120-122v AC lines.
So I switched to Edcor. A)well priced B) Made in the USA C) have 120v primaries. I use their output trannys too, very good products. - Pete
Magnequest 5504...now made by Heyboer to Mike's specs... this is an excellent PT and used my Horus 2A3 amps...
It's a shame they didn't rate the 5v winding at 3a. In doing that you open the design to also using 5U4's. If there is one component in a tube PS that does affect sonics, its the rectifier.
Or can the xformer do 5v @ 3a if another winding's current is reduced?
Usually that happens if someone pulls on the wires. The solder joint for the lead out wires can be easily fixed. I have had some very nice transformers suffer lead out failure. I do like the 300 series from Hammond. Edcor transformers are also reasonable.
What are you looking for the upgrade to do?
