hi,
we have a trident 80B without the transitors , this one is from 1987, the previous or earlier 80B version had BD517 BD518 BD519 BD520, we tried a replacement but the channel crackles when i push mute and pannorama switches, ...i suspect i got the wrong types,eventhough the specs match , more or less ...
now the question is, is there anyone who has rebuild their channels with the transistors WITHOUT these problems, if so WICH transistors did you use??
thnx in advance
