Title: Identify this Modulation transformer Post by: ke7trp on July 08, 2009, 01:32:45 AM This one ran two 810s with HK54s. Any idea of ratings? Any idea what all 11 taps are?
Thanks as always! Clark Title: Re: Identify this Modulation transformer Post by: K6IC on July 08, 2009, 02:03:24 PM Hi Clark,
I do NOT know anything about this transformer, but Peerless had a very good rep ... I've not Googled "Peerless", but have read somewhere that they were a part of Altec or associated with Altec. Have you Googled Peerless #######" ?? Often you can find some info this way. Also there have been threads here regarding measuring Mod Transrormers. EDT: - Just Googled "Peerless modulation transformer" The first hit had the fllg: PEERLESS TRANSFORMER CATALOG AL-1285-1 PEERLESS TRANSFORMER CATALOG 1953 Am off the the remote site, and you may have already Googled around, but, if not, Google is your friend - 73, and UR GK sounds great here, hope that you get the bigger rig going soon.

I did some more work on the GK and I got it runnig correctly with the D104 now :) The 6sj7 was causing me lots of trouble!
I did a search but could not find much info it. I will try again. I was mainly searching for this part number. Clark Title: Re: Identify this Modulation transformer Post by: KE6DF on July 08, 2009, 02:40:35 PM So what is the Peerless part number. I have some old catalogs. but I need the part number

Clark Title: Re: Identify this Modulation transformer Post by: KE6DF on July 08, 2009, 11:53:38 PM It's not in my catalogs.
In googling around I found a Chinese site with one of these transformers for sale. It said it was a 300 watt unit. No other specs. You should be able to tell by the weight. I think a 300 Watt modulation transformer should weigh somewhere around 30-35 lbs. Dave Title: Re: Identify this Modulation transformer Post by: ke7trp on July 09, 2009, 01:39:10 AM I think this one is more like 500 to 600 watts. Its 60 lbs. Also. It ran 810s. So that would point to the need of 500 to 650 watts. I will have to measure all the taps to figure it out. Should not be that hard. Thanks alot for your time and effort!
