People obsess about the color of their plates in the tubes. There's nothing wrong with the tube getting red it's supposed to. Its when they get white you need to worry

Ah shit. I liked him

usually when guys lose a tube that diode pops. usually explodes actually. Ive replaced a few myself. that and a new set of tubes fixes most of them. assuming ameritron actually soldered all the other stuff..

tbh, i never realized it was actually a dead short. I just always noticed it showed 0v. I always did it with a meter and a power strip with a nice on/off switch. quick flip, nothing, reverse leads, try again.

If you hook up two transformers out of phase you get 0v when you turn them on . Its then a simple matter to swap leads, and then label them. Alternatively, just rectify both transformers separately and combine the dc.

They always seem to perform fantastic locally

And just to be clear I'm not saying that any coax length fixes your SWR.

I mean, thats kind of loaded statement dont you think? The difference in measurement is easily seen with different length coaxes, especially if they are at weird multiples. Especially if you are looking into, say , the input tuning network of an amplifier. Im not saying youre wrong, but you are...

You are not an idiot but for that money i would have gotten an alpha 9500 with auto tune. Just under $9k. And you can put a brick on the key and walk away

The problem is multi faceted. You have a company that makes the cheapest versions of every ham product imaginable. They also fabricate alot of what they sell. Good labor aint cheap and cheap labor aint good. On top of that hams are cheap tbh. The only way to make a profit in the amp business...

The mfj antenna analyzers actually work really well when they work . And they are fairly intuitive for a few operations. Certainly simpler than a nano vna.

And that 7200 I think is not with an eiMac tube

They dont seem to put their best on the phone.. then again, maybe they do.

Even though their prices are literally 100% higher than they were less than 20 years ago on their amplifiers, it's still hard to find a comparable ham amplifier for the same price. Except for some of their bigger stuff, when you're looking at $8,000 for a 1500 A7 box. I mean at that point you...

It won't. I just got two. Im not mad, ill use them on my other Wilson antennas
