Norman Koren wrote a two-part series on modifying the PAS3 for Audio
Amateur -- it can still be found on his website. http://www.normankoren.com/Audio/index.html He doesn't do much in the audio domain of late. Koren improved the RIAA section of the preamp -- and it needs it, but at the expense of another tube which strains the power such that a little auxiliary trafo is recommended. Jung and Voorhis did an excellent article in Audio Amateur or Glass Audio on modding the PAS -- "The Last PAS" -- here's a digest of the power supply mod: http://www.tech-diy.com/DIY_PWR_LastPass.htm "V v" wrote in message ... Mark, I was in the process of rebuilding a PAS3 using point to point wiring and no boards. I'm not an electronics engineer by any stretch of the imagination, so it has been a process of copying, sketching, and (next step) soldering it all together. I'm writing this beacuse I am confused about a couple of things in your first post; I am hoping you (or anyone else) can help clear something up for me. I thought the PC6 was the phono section- no? I have only 1 audio source component- a turntable. I will not use any other inputs, nor will I be using any other preamp. I would like the PC3 to simply give me the gain I need (from the truntable) and give the volume control to drive an amp. I have already eliminated everything from the faceplate. All I have for controls are 2 independant volume controls- left and a right. I also have a power switch- that's all that remains. It already sounds so much better but I would LOVE to eliminate one of the boards (be it PC5 or PC6) if I could!! Could you please verify that the board you have omitted is actually the PC6. And, could you elaborate just a bit on how you hooked it up? Thank you. |
