[Amps] ARD 230A

[George]

Hello Luca, I had a ARD 230A, sold it a year or two ago.  From my 
experience I found the circuit board connectors had small pads and 
traces.  Consequently the circuit traces at the connections brake during 
shipment and vibration and need to be resoldered,
and or wires added to correct the brake. I found this on the main 
control board as well as the input relay switching board located in the 
RF cage on the bottom side of the tubes.  Also had this same relay board 
fall of the push on standoffs during shipment.
There were many brakes around the relays from vibration. Once I 
corrected these issues the amp was awesome, I kind of wish I didn't sell 
it.  One thing you might want to do it reprogram the EEPROM, it's at or 
beyond the limit for data retention time.
I saved the HEX file it you need a refresh, let me know.  Good luck with 
the amp, it's really awesome.

73,
George, K4GVT
