Mosfet Relay for speaker protection in Audio Amplifiers
As a result based on my experience as a serviceman of audio amplifiers,I have developed direct replacement of a standard mechanical relays Finder type 40.61.
This "relay" has parameters:
On-State resistance: 9mR
Maximum continous current 16A
Maximum voltage accros open relay 64V DC
Used mosfets has maximum continous current over 150A and peak current over 600A
It´s easy to use, just desolder old mechanical relay and solder new "SSR"
For anyone interrested, it would be possible to sell these relays. The price is 22 Eur/pc , approx 7 Eur shipping
Below you can find pictures.

I made a similar relay drop in for the Songle SLA relay some 5 years ago for my 5 channel HT amp . still working fine !
