Vectronics HF-600 (AEA LA-30) antenna switch
« on: April 13, 2020, 12:30:17 PM »
Does anyone have the make and part number for the antenna relay used in the Vectronics HF-600 (AEA LA-30) amplifier. Or a suggestion as to what i could use. Looks like someone has installed a regular Allen-Bradley DPDT relay in the unit i have here. Thanks in advance, Colin...

Generic relays work just fineYou don’t need an exact replacement.  Is the one on there not working?

Both of those amps have reached collector status. As I remember it is a generic 12VDC relay.

It works but input to amp shows higher than ideal SWR, 2.5:1 on all bands and had burned contacts before on cw using QSK.
