|Bradster||Can anyone measure their PT's DC resistance?|
In trying to use Duncan Munro's PSUD program to model power supplies (Marshall/Fender type) using Hammond transformers instead of OEM, alas, one needs at least the DC resistance of the Pri & Sec of a given transformer to use the program.
(kind'a puts a crimp on using the software to help select a PT 'eh?)
Would anybody with any of the Hammond PT's listed below care to toss a DMM on them and post the DC Pri & Sec resistance? (or on any of the Hammond PT's for that matter) it would be very much appreciated for the list I'm trying to compile.
(or any of the 3xx series)
(I have emailed Hammond but they have not replied)
And of course if you have any of the following Marshall or Fender PT's within reach I could sure use the DC Pri & Sec resistance on them to include in this:
T4145 DE (2203, 1959SLP)
1202-164 (old 2204)
1202-324 (new 2204 and 1987)
125P34A (100w Twin, Showman, etc w/4x6L6)
125P5D (SR w/2x6L6)
125P7D (BM w/2x6L6)
125P23B (Deluxe w/2x6V6)
125P1B (Princeton w/2x6V6)
Along with a list, I will create some matching *.psu files to use with the PSUD program, to post for anyone who is using Duncan's freeware Power Supply design program, and yes before you ask, people have asked this same question over on Duncan's forum, nobody's got the info over there.
All we need are a few kind soul's willing to take a couple minutes to measure these transformers and we can get a definative list useable with the PSUD software. Post it here or email me if you like.
