I had a T-38 too! Wrote some of my still favorite songs on it. I can't even remember who I sold it to. You are correct the unit was almost impossible to carry alone.Cool! I found this short video : Logic 7 Recorder
I had a Tascam 38 which was a beautiful piece of gear.. when it was fully operational. I wouldn't want one of those back for all the tea in China. Plus it weighed as much as a VW Beetle (with engine.. fully fueled.. and the high school's football team front linemen inside).
For some reason I assumed that everyone knew about Terry Witt. Lots of people recommend him. The other Terry that you need to know about is Terry Summers at Summertone who is the person to go to when you need your heads relapped.I’ve found a guy in the US who will make me a new pinch wheel rubber. I need to send him the brass centre and he’ll sort it, and he has the sizes too! Terry’s Rubber Rollers!
Had a look at a schematic Rob and the mic pres are simple transistor pairs, very similar to those in my Teac and I remember my son used to use an SM57 into the recorder with decent results, tape noise was above pre amp noise.This one has a lovely tone, light action and apart from the dings, in really good condition. Sounds great. less than a grand, including delivery. I hadn't thought about being able to do recording experiments? The Ferrograph has two ¼" unbalanced mic channels. It will be interesting to try these. The SM57 I bought in the 70s was plugged in this way - I didn't have any gear till the mid 80s that had an XLR input, but my recollection was that I could put the mic outside and record bird noises - I wonder what the noise will be like compared to modern kit? Good call.
