> Search for Heathkit and Kenwood TL-922 on the net.  If you can't find exact
> replacement you can buy a v. cap with equal or similar plates and re-plate.
> Some hams end up with old v. caps that have 6 or so plates screwed up from
> arcing or attempted "filing".   It takes about an hour to change out the
> plates once you get the device out of the amplifier.  I have done it twice.
> Re-centering or re-spacing the plates during final reassemble is important.

> If you melt solder well you may consider the Kenwood TL-922 QSK mod designed
