One more front.


Potato Cakes

So I had an interesting thing happen. Or perhaps unexpected would be more accurate. One of my 176 builds I used to do a record. Then when I received my matched 6BC8 tubes from Bowie, I did more testing, but then at some point of listening back through it, the input gain dropped. I messed around in the back of the rack and apparently the In+ connection was intermittent the whole time, so I fixed that but then I still had about a 10dB difference to the other unit. What it came down to is that the O-1 went bad, something I'm not sure how it happened since it had been working great this whole time. I have had transformers be faulty when purchased new, but never seen one go bad over time. Fortunately I have a pair of O-2 that I thought about selling but never did and after installing it everything is back to normal. Very strange but glad it was a fairly easy fix.

Thanks!

Here's both units up and running testing with some program material. I can't tell a difference with the controls set the same.

Thanks!

Hey Paul - great job in figuring that out! Thanks for sharing.
