1. With regard to the Z mod phono board, is the RIAA curve on the board more accurate than the Dynaco originals? If so, is it still compatible for use with the stock Dynaco selector switch (which I believe in the original design, has some EQ correction mounted on it that is used for the Tape Head and Special inputs)? I'd like to retain the use of those inputs as originally designed, if possible, yet still get the upgraded phono circuitry of the Z mod board...
2. With regard to the TCLA board, I know it is also available with an outboard circuit board that can be used with the original "dual mono" Dynaco bass & treble controls (rather than the modern stereo controls that it's usually pictured with), but will it work with the original PAS-3X bass & treble controls, that have the "drop-out" feature built in to them? And if so, is there still a need to attach an extra capacitor from the main board to the bass controls, as is done in the original PAS-3X build?
3. Is it possible to buy **only** the boards, with a parts list that contains the necessary values to stuff it with different caps & resistors? (I'm thinking that some upscale carbon comp resistors might be nice, if they'll fit in the space provided on the boards). If so, what are the prices for the "bare boards + parts list"?
Thanks for any assistance... I did searches of the forum, but I couldn't seem to find any definitive answers to these questions.
