I have a DY-88 that's in the shop with an issue. It has a failed Receiver Start Relay, K203 That's the relay used to activate the vibrator power supply in the DY-88 when the attached radio a GRC-9 or BC-1306 is turned on. The relay is in series with the filament string and when the radio is switched on the voltage drop causes the relay to pull in. The point being its not just your average off the shelf part.
Anyone out there have a junk DY-88 chassis that I can get the relay from? There are three relays in the back of the 88 and they are all plug in and labeled. K203 is the center relay and all the relays plug in so removal is no big issue. Just locating it. In the old days this was something that you would be able to order from Fair Radio without issue but today that's not an option.
