Hi everyone,
I purchased some new power tubes from Tube Depot online and received them today. I went with Tung-Sol 7581a and not to be confused with the 7581. I checked with PRS Techical Support prior to buying the power tubes to make sure they’d be good to run and I was given the thumbs up by Sean with PRS Technical Support.
Anyways I got the power tubes installed and I had to make the slightest adjustment to get them close within 30 +\- via PRS recommendations. Anyways here is a short less than 1 minute clip of the bias adjusted. I’m curious to know if these power tubes are close enough within spec for being matched or are they to far off? Are these acceptable? I was only slightly concerned with the power tube that’s
around 26, almost 27.
Thank you and appreciate all the feedback
