you would be most welcome to stop by. maybe bring one of your Technics so you have a known quantity to compare to the Tim DeParavinici modified one. that might answer your question.
Getting it across the border both ways would be a hassle.
Did you say one deck is modded, and the other is not? If so, swapping the same tape between decks might be the easiest way to do it?
However, it got me to thinking about a few things:
1) AS stated above, most prerecorded RTR tapes are indeed 1/4 track and most that I've seen for the consumer market are 3 3/4IPS. That obviously was to save tape when marketing to the masses.
2) What would of course be desirable is 1/2 track 15 IPS tapes dubbed right from the original masters, or from new live recordings, going straight from mic to master recorder with no digital interfaces. Analog rules, baby!
3) I am wondering though, how much a beefed up preamp/playback section is going to benefit a 30-40 year old recording? After all, the recording was made (usually in high speed dubbing methinks in the case of commercially sold prerecorded tapes) with 40 year old preamps and recording amps. Therefore the s/n ratio and THD, etc is limited to what those old preamps could do. I don't see how a 'new millenium' hotrodded playback amp is going to benefit these old recordings?
And no, I'm not trying to start a sh*testorm here again.
I would however agree that if the recording amp AND preamp were completely rebuilt, along with the bias circuit, you probably would hear a difference on a recording made on that deck.
