heathkit apache tx-1 meter

[NR5P]

Does anyone know a place to get a replacement meter for a heathkit apache?  It doesn't get stuck in any one position but will only have partial readout then I tap the glass and it jumps up.  I seem to have all the other bugs out of the radio, I hope I havent damaged the new power tubes because it's been lyin to me on the drive sometimes.  I've cleaned the terminals on the meter so it must be an internal problem. thanks.

I have had some luck once in a while by adjusting, very carefully the little teeny tiny screw at the center of the adjuster - this is the pivot adjustment for the movement.

Check first to make sure that the movement is not hitting the scale due to the rig having been dropped.

Hold the meter at various angles and use your breath to move the pointer... see if you can get it to hang or not. try to see what is causing it to grab. magnifying glasses might help here... bright light too...

Also, first take some contact cleaner (pop the meter face off) and spray the pivot points. They can take some lube... but you need the right stuff, non-gumming oil. the stuff used for watches is a best bet - ask a jeweler?? One might be able to get by with some silicone oil or synthetic oil that is suitably lightweight. Model shops may have such things... again a tiny drop is all that is needed, although you may be able to wick off excess with porus paper... better meters had jeweled pivot points, but I'd bet that the Heath meters were metal on metal... no reason to lube jeweled pivots...

this might work...

they do show up on ebay and hamfests...

I think this heathkit has a ghost in it with the problems I'm havin.  Guess it'll be worth it when I get it on the air.  I took the face off and the needle doesn't seem to be getting stuck at all seems real smooth.  Really weird, when I checked it and put it back in it's doin the same thing.  Either it won't work at all or it works and everytime I tap the meter I get a different reading.  It operates smoothly other than that not like it's getting stuck.

Check to make sure your zero set control is engaging properly instead of being offset and putting stress on the movement when the cover is in place.

Make sure static electricity hasn't built up on the plastic meter face.
