Available - LOT of 8 - Thermalloy TO-3 transistor covers - black plastic - USED.
These are a must for any audio gear with exposed TO-3 outputtransistors - see photo 2 Sherwood S-7600 with exposed TO-3 output transistors - this is a potential failure waiting to happen - shorting out of the transistor collector (case) will blow the output transistors. Many other audio amps have exposed TO-3 on heat sinks that arevulnerable for output transistor short circuit damage.
Now the fix -- see photo 3 of the S-7600 with a cover installed on an exposed TO-3 output transistor.
