I am keeping mine in, not to protect the tubes nor the transformer, but 
to protect the SB220 power switch, spares for which are not available.

My suggestion would be to contact the new owner of the 
harbachelectronics website to find the brand/type of the relays or just 
to get a new kit (which are in stock).
