Re: Hameg HM307-3 Cleaning and Repair
Thanks wme_bill. I will try a pair of BF256s as they are available locally.
I've been measuring the voltages on the BF458s in the final Y amp and they are all wrong!
What they should be:
E- 14.5V. C- 87.5V. B- 15V.
What they are:
T123: E- 20V. C- 47V. B- 21V
T124: E- 17V. C- 136V. B- 8V
I've pulled them and tested them with my DMM and don't show up as faulty.
Any ideas as what to do next?
