Well, I got the power transformer and choke for the 45/100 today. I’m shipping 56Tweed his JTM45 on Monday. I worked today until 4pm and got home to the Marstran shipment. The 1204-43 is huge. Weighs 13lbs. Checked voltages and I’m getting unloaded voltage of 388-391 on the low taps and 448-451 on the high taps. We’re using the low taps for tube reliability but I’d sure love to get another build and put KT88’s in it with the high taps. I’m disappointed because I had really nice vintage boards made for both these amps and found out that the material became conductive. I’ve ditched all the stock of that material because I don’t trust it. Sucks because I had 3 other boards fully perfed and Harwin turrets installed. I’m back to FR4 and G10. I’ll report as I make progress now on the 45/100. I have the transformers installed and wired. I’m finishing up the flying leads on the power board and getting ready to put both boards in. More tomorrow.
