Teac R2R deck A-4010SL
I am restoring a Teac A-4010SL deck that is labeled as a Teac A-4010S, but plainly resembles the SL models. However the RA-40 amp does not have the extra bias and equ switches to the right of the VU meters as does the GSL model. The ser # is 176165 and a code date on the capstan running motor capacitor is 70-11 (Nov of 1970), so this deck probably was sold early in year 1971.
I have spent about 3 weeks restoring the mechanics of the deck and now I plan to run a tone tape to check the playback responses.
Are there any Teac R2R techs that can help nail down history of my deck?
