Very possible. But my questions were as to the repair/restoration aspects.
The clip is of the amp supposedly finished, and ready to be shipped back to the owner.
Yet there seemed to be an issue with one of it's meters.
And the fan at slow RPM is clanking.
There are other things that leed me to believe this 220 wasn't repaired to an acceptable level.
I would think that making a clip of a restored repaired piece of equipment shouldn't be showing things are already beginning to fail during the making of a clip that purportedly shows a repaired restored amplifier. I'm still confused about the 220 Watts Drive recommendations made by the restorer.
I don't know if it's true, but to my knowledge the 220's recommended Drive is 80 - 100 Watts. Is the fact that it was modified to work on 10/11 meters by replacing or modifying the tank coil change the drive wattage to double+ of what it would be if the tank coil allowed for 10 through 80 meters operation?
2500 watt seems accessible for two z500's. I didn't know the rated dissipation for those tubes were over 1200 watts each, but then again I could be wrong. And even if they are rated for that type of output one would assume you would
see that output with the manufacturer's recommended input. I'm assuming if I drove my 4 watt Phantom with 50 Watts I'd probably see 1500 watts out of it. BUT NOT FOR LONG! That leads me to believe that 225 Watts is overdriving the amplifier,
I hate to say that it looks like a shotty job because my knowledge is so limited. On the other hand I have learned a lot whilst being a member of this site, and this amplifier seems like it won't be long until it's back on that bench once again. I could learn so much by this one clip if others with the knowledge will post the issues they see while watching this clip. I have a feeling there are so many more things wrong with this amplifier then a fan that clanks, a meter that seemed to stop working then fixed on the Fly, and the input output power shown on that bird . 73
