I have some boatanchors around my shack. Here are pics of some of them:





Halicrafters HT-41 (acutally nice amp, but I blew one or both of the tubes)



Ex-Varmit XL 1000 converted to a switch keyed 4 tube box for CW (still works, needs RF keying circuit and new fan, but doesn't put out much weak tubes?)



Bunch of old tubes. Take a look at the pictures, if you see something you are interested in just ask, they are all for sale, but I don't know how many of them work, however I think alot of them are brand spanking new, never been used. Bought out from old TV shop by a friend who gave them to me.







The Halicrafters HT-41 (85 pound plate transformer)

The Ex-Varmit XL 1000













Lot's of Tubes

Default skipper 300

Would anyone have a good shot of the inside of a skipper 300?
A view around the rear single tube where a wire wound resistor used to go before it blew to pieces ??
Sure would like to get mine working again

Uh, a "wirewound resistor" ?

Was it mounted on a tie strip parallel to the driver tube where the plate cap's wire connects?

If so, this was the plate choke. An Ohmite type Z-28 works for that one. Don't think there's a specimen here to serve as a "photo model".

And if there is no parasitic choke, made from a wire with a few turns around a 47-ohm resistor, your Skipper may have had a tiny ferrite bead slipped over the wire to the plate cap. If the bead is still there, it will do the job. Until it overheats, cracks in half and disappears.

If yours already did this, there will typically be no trace that it was ever there in the first place. Winding 4 or 5 turns of #22 or #24 wire around a 47-ohm 2-Watt resistor will take its place, and probably last longer.

My experience has been that the driver tube will go nuts and smoke the driver plate choke if it oscillates. If the original ferrite bead is no longer there, the tube is likelier to misbehave this way.

Palomar would use these tiny ferrite beads, slipped over the plate-cap wire in place of the more-typical coil-on-a-resistor choke coil. They worked okay until the first time they got hot, would crack and fall off. Forever.

And it seemed like such a clever idea when they first started doing that around '77 or '78. Until they started falling off the wire and disappearing. The coil-on-a-resistor "parasitic" choke just holds up better.

Yes i believe thats where and what it might have been.
I'll have to look into this.
