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...

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.

I think production stopped on these right around the time of the original post. Perhaps @nomadradio knows better. My opinion, they were cool 18 years ago when they were cheap. But for perspective, an ameritron al811h was $900. Now its ~$1500. Interestingly the cb market's customers have not...

Whut? Where can i buy a magic 572B?

Whoops, i thought it was captain kilowatts build. Now i see it was someone else.

Whatever happened to this project? Did it ever get off the ground?

Building tube based amplifiers is 95% metal work, specifically cutting holes just right and putting them in ideal locations. The electrical part is very little time honestly. I can build almost any size amplifier in about 16-24 hours working time. The wiring and tune up / optimization process...
