 Henry 2KD5 for sale
In good condition. I just recapped, replaced balance resistors and went through the unit. This has a pair of 3-500z Eimac tubes.
Asking 750$ pick up only off of I-81 near PA WV VA and can meet within a
reasonable radius.

Title pretty much says it all. I am looking for the back panel of an SB-220 or 221 HF amplifier. Parts attached to the panel are not important, but ok if they are included. Thanks for reading
