The newest clem is taking some of the improvements and moving them up a bit more... Im using Transcendar iron 5k, 8ohm ultra linear, a Transcendar 5H 300ma 60ohm is the choke, in stead of the 100ohm resister in the power supply I bought a 2nd 5H choke... Seems I have a high iron diet. The power transformer is a sp one I had designed at edcor... you now can get the same transformer without the design charge. its 330-0-330 @ 325ma 2 6.3v @4amps, 2 5v @ 4amps. Ill parallel the 6.3s so I can light up KT120 without a problem. The rectifier is a 5U4GB... should light everything up :-). The cathode resisters were out of stock at mouser.. for ~.50 more you can get 1% wire-wound which is what I chose. Coupling caps are Wimas bigger units. The power supply is spec'd at 100uf @ 450v if I remember correctly... I went to looking at found a 180uf @ 500v (Mouser part # 647-LGN2H181MELA50). I always use a 3" chassis and with short standoffs they clear... I am hoping that the additional 320uf of cap will be worth while.
Any thoughts/ feedback re using the 5H choke instead of the 100ohm 3watt resistor? Ive been told that mirrly increasing the cathode current does not equal more power, just more linearity... Is this true? If so, how do I get more B+?
Hope everyone likes... Im going to build one right after with same chokes and power, just with edcor CXSE iron I got used.
Thanx.
