First, I want to thank everyone for helping me get my TSE up and running. It sounds good!
Now that I have it built, I would like to make some changes so that I can check and adjust the bias from the top. I have used 1/4" phono jacks and plugs on another amp for the test points, but I would like to use something that I can just stick the DVM probes in. It seems that I have seen red and black sockets somewhere for this but I can't remember where. Any thoughts, ideas or suggestions?
Also, does anyone have a DigiKey/Mouser part number for a multi-turn trimmer pot to replace the single-turn stock ones that are used for bias adjustment?

Thanks for the help and suggestions. I am leaning towards Digi-Key pn 501-1346-ND. Thanks for the concern Boywonder, but I have no little prying hands around the house. Also, the ones I am looking at are insulated on top with the holes only big enough(2 mm) to get the probes in.
I wish I had these installed for I now have distortion in the left channel. I have changed everything - cables, preamp, speakers and input tubes - and the problem remains. However, I have not switched the 300Bs around to see if the left one is causing the distortion. Is it ok to switch and run them for a short period without checking/verifying that the bias is good?
