Pull the cover off, take a photo of it, and post it.

The keying and antenna relay circuits are pretty much the same on all three Maco mobile amps. For that fact almost the same as in the base units also. You do however have the power relay in the mobile units that the base does not. This activates the high voltage power supply...

I don't think I have ever seen anyone use heat sink material for plate caps.

It sure sounds like someone lit a fire under his tampon.:scared:

$15 more? How about $25? :headbang But still a better deal and antenna IMO.

If you use an external "peak" reading wattmeter does it still show to be backing up? On some radios I have had to play with the mike gain and compressor (if it had one) in order to get any forward movement out of it. Like it has been already stated most of the time if you lower the dead key...

Go to Home Depot or Wally World and buy a circuit tester for usually under $5. It plugs into the socket and lets you know right off the bat if it is wired correctly and if the ground is present. You can measure the AC from the coax connector shield to the case of the radio to find out how much...

That's it. Use a screwdriver with a well insulated handle. Odds are if the amp has been off for a while (as a result of the POP) the capacitors are discharged. But don't take any chances. The best way is to ground the tube caps out through a resistor, somewhere around 100K or more to slowly...

All it takes is one speck of dust thickness to cause an arc. Possibly the parasitic choke on one tube is cracked? It is strange however it does not do it while keyed. But like someone said in a previous post the HV is at it's highest point while not keyed.

Maybe one of the parasitic chokes was just a little to close to ground? Check the distance and if you can reposition them further away. I'll try to look at my 2100 and see if I can see anything else that might be suspect.

Just remember two days from today, tomorrow will be yesterday. Things look better that way.............or either through the bottom of a beer bottle.

Looks like Freecell has been banned. About time.

The JE/LQ are the same tube. Initially the JE and LQ were produced by themselves but they were so close together in specs they got combined. The MJ is a more ruggedized version of the JE/LQ and has a little more plate dissapation. You will get more power out with the MJ's but you will also...

It sounds like you have a tube with a grid short. That will produce what you describe. Check the tubes to make sure they don't have leakage. Maybe a cap in the HV supply? Does it do this in low and high power? I have had tubes cause this problem many times before.

I think he was last seen getting $5 worth of gas and a road map to Idaho.

This sounds like a good plan if it can be implemented. It puts the ball in his court to whether FreeCell gets canned or not.

Let me guess..........................next is the Mauldulator AM STEREO Real Time Processor. Of course if you get that everyone else will need to get the receive version of it for true Stereo reproduction. Coming soon to a KMart near you.........:headbang

That's right........................"EXIT ONLY".

Trust me, You would rather take a warm shower with Obama than to hook up with her. She makes Lorena Bobbit look like Mary Poppins.
