With the E series, definitely. However, the L series includes these diodes...
When faulty, the E series give high output because the driver leaks heavily or goes short (never had an issue with pass transistors). However, this one is giving no output.
To the OP: what voltage checks have you done? The manual gives plenty of readings, so that's a good start. There are no "stock faults" as such - you're going to have to dive in. If you don't already have it, the manual is here: https://www.vintage-radio.net/forum/...08&postcount=2

Thanks all, I've done very little as I've been too busy at work at the moment, but I'll probably get stuck into it tomorrow.
