Yaesu FT101ZD

My Yaesu FT101ZD is from 1982.

The transceiver is the MK3 version with the WARC bands.
The previous owner was my father who is also radio amateur.
He bought this transceiver new in 1982.
The transceiver has few transmit ours and is in mind condition.
I cleaned all potentiometers en the deck switch.
I replaced the "killer condensor" in the final.
it's the condensor between the anode of the driver 12BY7 tube and the first final tube 6146B (2 pieces).
The condensor is originaly an 1000pF 1KV
I replaced it with an 1000pF 3KV.
This part will fail in time and puts then 300V on the grid of the 6146B’s, who in turn pull all the current they can get,destroying the tubes and the power transformer.
if you are
not nearby, rendering the transceiver useless.
