Hi everyone!
I just bought a 2510 and I am having an issue. The 45 loads properly, and the record plays fine at the beginning, but starts to sound garbled the longer this plays.
Has the amplifier been rebuilt? If not, I would turn it off and not use it until it has been. Failing capacitors will cause distorted sound and eventually damage expensive tubes and transformers.
Would this be needing a new needle, or a tone arm adjustment?
Very unlikely.
Just because I am curious, what tool are you using to measure needle pressure? The manual says to use a Graybar 70-D, but I can't find one of those anyware. Are you using digital VTF scales, and if so how do you use that when the record is vertical?
P K Neuses N-10 spring gauge (AKA Western Electric 70F). The 70D is too stiff to measure 5 grams precisely.

Graybar can get them but is unlikely to stock them and they'll likely be pricey there. Victory Glass has them in stock. https://victoryglass.com/product/pk-neuses-cartridge-0-to-10-gram-gauge/
