Their early (Maynard, MA-era) and even their later (Woburn, MA-era) SS tuners were better than OK.
Nice looking and solid performers they are. They have no relation IMO, with the gear made later.
The T-526 was one of six that were offered in 1979, being the fourth from the top in regards to price and specs. In descending order, 590T, 570T, T-527, T-526, 530T and T-516. The specs for the T-526 are;

I did not own this tuner, however, I owned two others from this line and found that they belied their specs, which is common for Scott gear of this era and earlier. They both were quite musical and solid performers.
Unless you have considerable receptrion challenges to overcome, I think that you will like this one and any from this line. Their specs and retail price are very close amoungst that years offerings.
