Ned Carlson has started his own outfit, no longer at triode electronics. (Left about 2 yrs ago)You'll find him here: http://www.tubezone.net/index.html
Still no answer on power a power supply........
I really just need to know if the newly designed power transformers for the ST35 are copies of the original , which seemed to run hot from many accounts I've read, or if they are new improved versions that will run cool.
If so I'd like to order one from triodeelectronics this week.

I remember a couple of years back when these were released, there was a bit of talk on AA TubeDIY about them being redesigned to get over the overheating issue.ThSpeakerDude88 said:
Also, whilst I have direct experience of them, the 2 series Hammonds had a rep for running hot according to AA pundits. The 3 series were reportedly better. Unless cost or weight are an issue, I buy the biggest iron I can.
I have used the 3xx series in several projects without any problems. They have been quiet and run cool. I have an amp in my office that gets switched on at 6am every moring, runs until 5pm, and except when the air conditioning went down, never gets more than warm to the touch. Without the ac it got noticeably warmer, but not hot. Never tried the 2xx, heard too many stories about running hot, but I don't recall reading a lot of stories about failures. I have also used the angela universal in a couple of amps - they are very quiet. They do run a little warmer than the 3xx hammonds, but nothing to worry about.
well I ordered the one from triode electronics. Matches the Hammond OPT's perfectly!
Now I have a question about placement. On the ST35, and a lot of other amps, the power transformer is always at a 90 to the OPT's. Does this really reduce hum enough to warrant this location or was it originally done to save room? I think it would at least look better with them all in a neat row, like mcintosh amps.

Don't you hate those days? Once I get the chassis polished I'll post some pics up here. Cheers!
I just got my hands on a 373BX. Compared to a 274BX that I also have it is quite a bit larger and heavier! Something to think about. I got it dirt cheap, but will probably crush the $6 cake pan I was going to use as a chassis.
It's likely a get what you pay for deal. My 274BX hums like mad, gets very very hot, and it's primaries are rated for 115v. I haven't wired up the 373BX yet, but the word is that they run cooler and don't hum like the 200 series. 120v primaries are a plus as well. Check out Edcor's offerings too. I haven't had any experience with them, but plan to purchase from them soon.
