@Shockwave i feel like i read a very old post from you, or perhaps @nomadradio about using tube testers to test big boy tubes, like 8877, 3x3, yc156, 35b etc... obv you need to supply the filaments in an outboard manner but cant you hook up these large tubes to a hickock or similar and get a...

Yeah, this sounds like a good project for 3D printing

Yes

Id be curious if a visual inspection of the input network would show you something. Sometimes they forget to solder stuff at ameritron.

I would take a trip to a vinyl shop, they have all types of textured vinyls that you could just cut a piece and wrap the bottom of the meter in, also, a more readily available solution, would be something called gaffer's tape. You can buy in wide widths on Amazon and it looks fantastic...

I never understood why they use that lower temp red and green wire. If they used the 200c brown stuff itd be better.

Use business card stock.

Ive been wanting to add this meter to cobra radios for years

As far as the phantoms go, and I may be confusing it with a maco, wasn't there a variant that had like five knobs on the front to tune to get the thing running? For some reason I seem to remember a phantom that had five things to turn. And I never really saw a good explanation to its tune-up...

Thats not saying much.

I have 4 ready to go right now. Built with actual sockets to enable easy service in the future. 600+w pep with 75-80w pep drive. Ymmv. 120v plug in the wall. $1000 ea. Plus shipping Video explains it all

Id call jeff and see if hed warranty it. He likely will, hes a reasonable guy.

Replace the caps and bleeders. If im not mistaken they are either 180 or 200uf 450v or 500v caps. Use 100kohm 5w resistors for bleeders.

Good 3m tape is rated for 600v per layer, a few good layers on each end will insulate it.

I would bet a close inspection of the caps once removed from the pcb would show a tattletale black mark somewhere. Disconnect the AC leads and secure them out of the way. Maybe with some electrical tape on them. Turn the supply on and you shouldn't have any issues if the caps are the issue. If...

More like 800-900vac

Both responses are correct, also one thing to take note of is that your state of tune will change depending on the amount of drive you apply. So if you tune this thing for one level of power, it'll change a little bit if you lower the drive significantly

Ha ha ha ha

Dont worry about that, i get stuff from there all the time. Packages get through no issues.

I mean, if it literally "just needs tubes" i might do it. But if i had it, spending 125-250 for a set of tubes to maybe get 700w on am... I dunno. A gi7b would make same power with that supply and they are $30.
