Tascam 38 head issues

[DJ MIGGY MIGS]

Hey y'all. Im back here many years later! Currently servicing a Tascam 38. What i hoped would be z simple job turned into a full out restoration project but my client is still in for the adventure so here we are! After working through many problems I believe I have bad relays on all of the channel cards. Input is fine, sync is fine, but repro is dead silent while recording. However, rewind and playback on both sync and repro are working perfectly!

Wondering if anyone can help me work through what some modern relay replacements would be. I've been trying to find datasheets for the OG relay part #'s but no luck. I know they're all 24VDC, and K102 is a reed relay. Beyond that I dont know if they're SPST or DPST, etc. Any help on this would be greatly appreciated!

While the deck is on it's back which is how they are normally worked on it is at the top of the stack 1-8 going down. There is a relay if it has not been mentioned that gets flaky for switching the same preamp between syn and repro. it is a tiny closed small signal 24V relay. G5V1 24 volt relay. When I am in a particular mode and signal is not sure I tap the board edge and that relay make contact and will signal that it is ready to be changed. I am presently replacing the head relay in a A4300 with two of these relays.
