Pioneer AM/FM Home Tuner model TX-960

[Schematic Schemer]

Hi,

I'm looking for schematic diagrams, particularly with DC voltages included, for a Pioneer discrete home tuner. Model TX-960 This is a stand alone model, no amp. But it has PLL circuitry with independent RCA phono output jacks as well as decent antenna inputs.

The unit still works perfectly on FM stereo but the AM crapped out and it is mainly what I use this unit for. Recording talk shows on at odd hours when I am not awake.

I'm sure it's something small but would rather have a schematic before I pull the screws. Would appreciate hearing from anyone who has repaired this kind of equipment before as I suspect it's something minor and common. Usually PS's go on these types of things.

Thanks!

I highly doubt he's going to be able to buy it for .99 cents though.

Of course not. That's the "current bid." He'll need to do like it says: (Enter US $1.04 or more).

Yeah, I saw that. Vintage. Still could blow out 2 mins after I plug it in.

I'd rather put new parts in some thing I owned especially since I know it has sat for the last decade, unplugged. Maybe even pull out my old college books and re-remember the diagrams and flowcharts.

In that case, any idea what's a good PC input type Oscilloscope replacement these days? Haven't researched them in awhile but I hear the prices are waAay down.

I had a dual trace retired air force unit but when that blew I had no tube tester.

Edit: yeah, the postage is $11 alone...

Let's hope your problem can be solved with standard off-the-shelf resistors, capacitors and transistors, and hope that the ICs, IF/Detector coils, AM antenna, etc. are in good shape.
