" One needs a meter although it works without as I put a resistor in place of it.If you look at the schematic,it is basically in series with the tied output tube cathodes to ground.The one meter you see is actually a NOS one when I bought that amp.You can see it in the first photo.My question is,does anyone have a meter and if not,is there one that will physically fit in its place..I'm thinking 130ma meter should sufficient.

That has been going on since the beginning of electronics and today's ham radio operators are the worst offenders when it comes to gadgets on their equipment.This is why we call them appliance operators.Many just go out and buy the biggest and most expensive transceiver with all the gadgets they can find and most have no clue on how those gadgets even operate or what they do,or if they are even needed.This guy buys this Icom and it was almost 11k pounds which would be about 15k USD I would guess..Anyway,he does have a beautiful 70ft tower with nice multiband antennas and the tower motors up and down but when you look at his other stuff in the shack,you just know the guy is in over his head when he starts talking about it's operation..He does use some external compression and tailoring of the audio.He claims his audio is as good as the BBC.While I have heard some really nice signals from side band,they were using a lot of commercial broadcast quality processing equipment to get there..Everyone of these radios like this top of the line Icom with so many useless gadgets,sounded buried compared to a less expensive radio that wasn't feeding a zillion sections to alter the signal.I'm puzzled as to why a radio with all these features need all the external processing? That's why you get tube transmitters and transceivers and you're ready to go.

was into amateur radio as well. He lived in a very nice section of Dallas and had a similarly huge antenna which fortunately was somewhat obscured by nearby trees. When a neighbor asked about it, he replied "I have a big screen TV!'
He was also a member of a local club that included an ex-CBS broadcast guy. He got some of his stuff from that engineer that likely pushed the limits on allowable power. There were times when a neighbor's sprinklers would spontaneously go to work. :)
One time this lady was taking a bath and this story was in a 1956 QST magazine that I have an old collection of..Anyway her neighbor was a ham and this was in Bismark North Dakota..He was coming thru the pipes and this was an older home where lead and or copper pipes were the norm.The pipes became a tuned oscillator and it was picking up his signal on the six meter AM band and the lady flipped out..You would only hear it when there was water in the tub and you were in the tub.

I'm waiting for the headline about the ham with a mobile KW who keys down next to a self-driving vehicle.

living in Connecticut working for Westinghouse..He came over in his brand new Buick Century wagon with the wonderful 3800 V6 but everytime he would key up his 2M/440 Icom transceiver at the light,his car would stall.It didn't do it as much on the 5 watt setting but on the 10 watt and 50 watt setting,it would do it religiously.We went into the Buick dealership and being the car was in warranty,I had them change out the ECM. Unlike Ford and Chrysler,GM computers were exposed where you could change the Eprom.Keep in mind this was the old OBD 1 system.
It appeared to cure the problem for two days,but then it was back stalling again on high power.After checking parasitic draw and voltage at the battery when the Icom was keyed on high power,I decided to do a Hail Mary.I pulled the ECM out of the car and wrapped it in 10 layers of aluminum foil because the crystal in the ECM,was triggering a command to disengage spark.Once I put the thing back together,there was never another issue.The foil shielded RF in the 146mhz range which is where the problem was happening..Long story short,the dealer said it would not void the warranty so Dale was happy about that.

Looks like an EIMCO if so I may have something or know where to get 1 or 2 if you could get a better pic of it let me know.
Thanks AJ
I think I will put the meter out and give you measurements..It doesn't mount like a typical meter where on many you would have threads coming out of the four corners and then you slip it thru the holes and put a nut on each corner.It has a like a T bracket.

Can you tell if the existing meter is labeled EIMCO (Electrical
Instrument Meter Company)????? Looks like it might be. If so,
you can find a pair, with some patience on the internet. FYI,
these meters were common in some industrial equipment so they
can be found. I found a pair to replace bad meters in my Heath
W-6s. Good luck
Regards to all,

and the one with the round meter..The round meter looks much more natural in the amp than the stock meter..

I agree, the original looks like a cheap Emico meter on a battery charger. I'd look for a matching pair of round MIL meters and have the scales redone. If you buy 1mA or less, you can locate the shunt at the tubes.

It also acts like the meter on the old cheap battery chargers in that the needle bounces around.

How in the world did you ever get a pair of them? I lucked into one almost 20 years ago when I had just started in the hobby, and sold it before I knew what I had. I have always regretted it, and I have never seem another, let alone a pair. Is the iron in them as good as I think it is? Now I really am envious Mike!
so I just told the hands of fate that I'm entitled to a pair by nature of birth. LOL.
All kidding aside,I have 700 in this pair because I bought them separately back in 2010.

I wish I had your problems Mike..... you have so much cool gear! I have a bunch of meters, but alas they are all of the round variety. Good luck with finding a replacement.
