If the tube is rated fo 3.5 kv, it should hipot a lot more than double that. When driven to max out, the RF voltage in the PI / PI-L will back feed via the plate block cap...and superimpose itself

I have a beautiful Dentron MLA 2500B Amplifier that I purchased some years ago but never turned it on and now will never need to use it. A choice I have is to list the entire untested amp or list the

Hello 'Selcor', Wednesday, March 6, 2019 Thanks a lot for the comprehensive reply. The amp uses this transformer, maybe with a doubler or tripler, it's hard to see without some dismantling. What HT

The 3CPX800A7 is essentially the same as the 3CX800A7. The main difference is that the 3CPX800A7 is pulse rated and has a higher arc-over rating. Consequently, it can handle higher plate voltage. The

05/03/2019 20:55 I have acquired an NMR linear amp made by AMP UK using two 3CPX800A7 tubes. It's bought "as seen and untested" Apart from the RF power meter smashed and a coupling centre insulator

For the lower voltage 5490 (under load) B+ supply for the 3x3 tube, I re-configured the myriad of 10,000uf filter caps. This also includes the 78 vdc vdrop, with the 1.5 A flowing through the 52 ohm

Duncan Monro... who is a ham, who wrote the infamous PSUD-2 power supply program, is also going to add a bunch more features to the upcoming PSUD-3 version. Data for the PRIMARY side of the plate xfmr

Same here ! The snakes were good selling when new... out of sight now. Nowadays, a 9 in the pocket... better than nothing ?? I wonder. Don W4DNR Quoting "'Roger (K8RI)' k8ri@...

Looks familiar.? I think it was on/in one of those Stainless Steel Delorians:-D Ran on garbage. Neither sold very well. That goes in the category (wish I had done differently) with my 2 Colt Pythons.

Awesome!

My Harris FM20K has high voltage wire encased in steel flex tube. Impossible to get smacked with it. John Lyles is the real deal. He's also one HELL of a nice guy. I'm on a couple lists he frequents.

Glad to hear you are still kicking. That makes my foray into getting poked with 408 AC and 540 DC as mere tickles although after the 540 I woke up on the basement floor. I had been working up on the
