It's been over 40 years ago I believe, but I think the final solution was to wrap a solid wire several turns around the contact where the wire was soldered.? There were sharp points that made it

I was told, years ago, after experiencing the same malady in a Yeasu 2100 by a more experienced ham (sic) to never change bands with the amplifier on. Seemed sorta silly to me. I heard later on in my

So, did they fix the problem, and if so, how?? Heftier contacts or bandswitch? 73, Steve K0XP

I had one of the first AL-80s quite a while ago.? It was very good at vaporizing one of the bandswitch contacts when operating on 160.

Jim, I have one of these amps. With low drive from the exciter, the "load" will often end up all the way left/meshed. That's why I asked the op that. Bob W4JFA

I emailed you directly yesterday regarding the parts I am looking for. Did you get it? Sent: Sunday, December 10, 2023 12:10 AM To: [email protected] Subject: Re: [ham-amplifiers] Ten-Tec

It appears the padder(s) are not being switched in on 40-80-160m.? BUT u have the issue on all bands.? It's as though the load cap isn't even in the circuit, or lousy tank coil coil connections.

Here is part 7. The 160-15m manually tuned, tuned input is now complete. And yes, the input swr is dead flat across each band . https://www.youtube.com/watch?v=ev-648v_G0I

Here is part 6, where the manually tuned, tuned input is almost complete. https://www.youtube.com/watch?v=_V8om_cRk-o

Here is part 5, with the manually tuned, tuned input + input RJ1A vac relay, input coax etc. https://www.youtube.com/watch?v=sk-nmCjWa7I

This reflector allows photos; it might help if you showed a photo of the wafer you need, as well as the spacing between mounting holes and the total number of positions. But I wonder if MFJ doesn't

Here is part 4, where the fil choke is installed, rated to handle the 78 amps CCS of fil current....and work down to 160m. https://www.youtube.com/watch?v=UWR39bxa_64

Does the group have a source for the progressive shorting band switch wafer on the AL-80? -- 73 Nick KC0YKO

Adrian, Tom "Rauchen Verboten" W8JI cut way back on his drinking, and now most of the stuff on his website passes muster. We need to find somebody new to kick around, hihi. 73 Jim N6OTQ

I'm curious, how much drive are you driving it with? Constant carrier drive? How much power out? Ig and Ip? Bob W4JFA

There are 2 x chinese factories. One has a 12% failure rate.? The other has a 70% failure rate.? ?The good 3-500Z's all have the white base...and not the brown base. The 3-500Z's that Tom at CTR

I may have what you are looking for.? This was built by Heyboer over 20 years ago, and I've never needed to use it.? Still in it's original shipping box. contact me direct for more info ron KA3JIJ

I have had good service from RF parts. Ups broke the tube in shipping and it was replaced no issue Brian
