SHP Mute Relay

[paradisecs]

Does anyone have a replacement part number for the mute relay?  One of the units I've been refurbishing (not full restoring) seems to have a buggy relay.  I took it apart and cleaned the inside and the outside contacts but I think it's still acting up and not completely closing the circuit.  It's probably in one of the books, manuals, or guides I have but if it is then I keep missing it.

Which model amp BTW--it's in everyone of the Service/electronic parts lists I have ever seen (a "k" #)but where are you going to buy it today ?

It is a 600ohm, 24VDC cube relay.

The only thing "special" is that the two muting contacts are bent so they close just ahead of the trip contacts. This eliminates the thump that can occur at trip-off.

I've used dozens of this type of relay for decades in speaker, signal and power switching. Once the contacts are properly cleaned, I've never had to revisit them.

What problem are you having-?
