FM reception?
Seems pretty good. It will pull in most stations.
Signal strength?
The signal strength goes up to nearly full scale on the station that is normally the strongest.
Stereo?
Nope, does not work
Quartz lock?
Nada, does not come on.
Fine tune?
No, none of the three lights work in that set.
All power supply voltages good?
All power supply voltages are good.
AM?
AM seems to be working ok.
What happens when you push the multipath button?
I will try that tonight.
What adjustments have you made?
Only adjustment I have made is to the lower coil on the quad coil.
Like I said, it does change the voltage level about 20 mv, but the meter swing is small with about 4mv change when tuner is turned off strong station.
What parts have you replaced?
In the tuner, nothing other than Pa3001 chip with HA11225.
Do all other functions on the reciever work?
Yes, the receiver seems to work in all functions.
I have the equipment needed to do the test bed with the other tuner board. I will work on that this weekend.
I have not pulled out the quad transformer to test it. I will do that this weekend also.
I have always changed caps in the tuners on Pioneers that I have worked on in the past 2 -1280s 1 -1250 1 -1010. You are right, they never had issue after recap. Thing is, they worked before I started heheh.
B & D said the HA11225 was a sub and so did the Pioneer site. It seems to be working as good as the PA3001a I pulled, so.....
Thanks for the input guys, I appreciate you coming back to this mess!
I will post finds tonight.
