OK, now I'm even more confused. I studied the Riders schematic more closely and my set is a combination of the TS-4 early and TS-4 late.
The TS-4 early has the big 0.03 mfd HV vertical caps and 6S8GT in the audio.
The TS-4 late has 0.005 mfd HV vertical caps and 6AL5 + 6SQ7 in the audio.
I have the big 0.03 mfd HV vertical caps and 6AL5 + 6SQ7 in the audio !
Also, thanks to your tips I was able to get the masking tape off
Window cleaner with alcohol and ammonia did a good job on most of it.
Then, alcohol on the residue. After that, Howard's RAF and Feed n' Wax.
Not too shabby. Of course, all the dings, scratches and chips are still there, but it beats refinishing.
Notice it doesn't have any side caps near the control panel ? That's another difference I just discovered.
All the other VT71s I've seen had those caps that covers screws which hold on the front near the bottom like this.
However, in the set, the control panel is held on from behind by screws.
I think the earlier design is much nicer looking.
