It sells online for $20 (PDF 2 pages), did anyone purchased it? Are they clearly readable? Is it worth it?

They say it's for the 931 2nd edition, it's what i need, but i know there are different versions of the 2nd edition... hope it's the right one :blink:

The only Lasonic schematics I know of are for the TRC-935 at the end of the owners manual (on the Boomboxery library)

I don't even think the company's CEO had it, and made a copy for himself when it was shown to him

AnalogAlley sells an actual full service manual for the TRC-935 so at least for the 935, a service manual did exist. Too bad the 935 is not nearly as popular a model as the 931.

The 935 and 975 are very similar, at least in decks, main board and tuner. So if you got the 935 manual, you could check 80%+ of the 975. Only real diff's is the clock, EQ lights on the 935 and the LBS circuit on the 975. All deck belt layout is the same.
