Our Total Power Control board fitted to a Silverface Twin Reverb 135W. This tames this very loud beast into a bedroom pussycat.
The keen eyed will also see that the original wax/paper eyelet board has been replaced. The original board had absorbed moisture and become conductive, rendering it useless. We designed a top quality FR4 fibreglass PCB to replace it.
Sorry, we can’t do anything about the weight.
