I can tell one possible cause for burning out the pin link someone was over driving the amplifier. I have seen it many times. I have even did it myself

I was going to run 2 D&A transformers in parallel . In a phantom there is 850 v at tubes.

Thank you nomadradio. i am going to give it a try. Amp does not work now . I may ask more questions later.

I am looking how to identify the wiring coming out of a D&A Phantom transformer. I am going to try and use this transformer in a Apollo 500 amp that I have that fried transformer. I see 2 reds, 2 greens ,grey, and others. Thanks

I have 2 SB220 amplifiers. SB220 number one when I put some drive to it every now and then it sparks at tune capacitor. It will make a hum or spark and meter shows 2000 low and 3000 high . It does not spark or hum every time and works great other wise.... Any suggestions to problem????? The...

I have a Apollo 500 and the transformer is bad it is a 1300v can I replace it with 2 transformers out of a D&A Phantom they are around 850v i believe. Here is one from Apollo.

Thank you nomadradio I will tell my friend. It is at a shop right now that told him it was bad so we do not know if 6 or 7 wire. I will probably have to change it out for him but do not really want to I do not like working on that really high voltage stuff unless it is mine. Thanks again sir.

I have a friend that the transformer went out in his Drake L4b amplifier. It has two 3-500z tubes in it. Is there a after market transformer that will work in it? Or does anyone have one? Thanks

I have a Antron 99 and a Imax 2000 hooked up here in Michigan and both work great on 10 and 11 meters plus have weathered the hard winters here with no problems. Best antennas for the money period!!!!

I would go with the Phantom. The 6lq6 tubes are easier to find and it is easier to work on if a big if it will ever need any work. Tune it up correctly and do not drive the snot out of it and it is a great amp. I have 4 of them myself.

I am running a 4 element Gizmotchy beam. It was not expensive and easy to assemble. I am now talking farther then I ever did with my Imax 2000. I have people 35 miles away and on vertical I can hear them talking on a stock radio running no power. I like the Gizmotchy because you can add...

A friend has a Palomar 300 linear amplifier when he plugs it in a recently installed GFI it will trip it so amp will not get power and work. The amplifier has been taken to my home and plugged in a regular outlet and no problem. Is the problem the GFI wiring or is amplifier not wired correctly...

I have 2 D&A triple Stage Phantoms and 1 Dual Stage they are nice amps and I use mine everyday. I find trying to tune a tube amp using a average watt meter a waste of time. Get a meter that reads PEP and it will be a lot easier. Just audio into amp and tune all to highest readings then back...

I picked up a Icom IC-746pro and as I am using the VFO tuner it skips numbers. If I mess with it I can get to channel frequency I want to. I have seen used VFO encoders on ebay would replacing encoder fix my problem??? I also read that these radios do have problems , it is worth the 125 dollars...

Thank you nomadradio.
