Schematics

Absolutely not.

Well, that's about the silliest question I have heard.

It may be naive but I do not think it silly. I have usually tried to get a service manual and schematic for my equipment, especially if I plan to keep it for a long time or if I have thoughts of modifications.

A few years back, I had an input noise problem with a Pioneer Elite tuner and I asked a local dealer/tech if he would look at it for me. He said that it would be pointless without a schematic because of the complexity of that unit but, when I said that I had the service manual and schematic, he readily took it on. Cost me 1 hour of his time and about $10 in parts. That was 12 years ago and the tuner continues to work superbly.

Schematics are a business all by themselves...
And NO , I do not think the company is required to even provide them for sale.
I am certain a lot of small companies just do not create them. The big ones used too.. but who knows anymore?
A few companies offer them for free in detail on line.
So it is all over the place.
Used to be SAMS photofacts offered all of them for a price.. but even SAMS is falling apart.
But you want a TV schematic for a 1953 Philco... go to SAMS... A 1972 Realistic eight track.. SAMS...
