Dear Nick, 

no unfortunately I didn't had the time to work on my BM lately. But I had ordered a new rectifier from a local supplier that is due to arrive the next week. Just to have one in spare in case it really breaks down under load. Doesn't cost a fortune so it doesn't matter to buy one. We're short on staff at work but next week it should return to normal so I can spend more time with the BM again. Also I will look at the safety resistor and have a close look at the PCBs itself for cold soldering joints and will measure the transistors on the back besides the STK. Will be reporting the outcome of course ;-) 

Very best regards

Tobias 

Hi Toby (Tobias)

As it looks you're located in Germany; may I ask where (north, south...)?

I am located in the "Schwarzwald". If you are close we may look into your 3300 together. I do have an 3300 with burnt processor which we could use as a donor.

Not a lot of time for me as well as I am self-employed so sadly can't dig deep into your BM remotely.

Best,

  Gunther

Hello Nick, hello Gunther, 

many thanks for your replies. Unfortunately I can't take the chance to look into my BM together with you since I'm located near Hamburg. Last days/weeks I had too much work in the office with people being on sick-leave and so on that I couldn't had the time to look into my BM again. Also the replacement rectifier was sent to the wrong address so I still don't hold it in my hand. 

Gunther, If I need some parts that I can't get here from a local store I would like to ask you for donation or selling those parts to me if ok for you? Money for the parts and postage shouldn't really matter at that point. 

There were some questions open by Nick: Yes, I'm fitting slow-blow type 4A fuses when replacing F2 and F3. I'll also be looking at C65, C66 and C74 as soon as I have the chance to do so and also check the R110. The other one discussed here R123 showing perfect reading on the meter. 

Anyway, won't give up on the BM and just wanted to let you guys know that I'm too busy these days to move on with the BM.

very best regards

Tobias
