Default Re: Ferguson 382U Firefly not playing ball

1N4002's are not signal diodes so probably will not bias on correctly. Actually I've found a good s/h Mullard UABC80 that you can have. Even if it doesn't cure the problem at least it will eliminate your replacement valve as being the cause.

Let me have your address by PM and I'll post it during the week.
