FYI,
I am glad everyone on the forum helped me out on the prior 1010 rebuild. That I am truly grateful for that help.
This 1010 was my FIRST pioneer purchase about 2 years ago from a fellow just 45 minutes south of me. It ran great but the stereo FM went out. All I had was mono on FM. So me being a newb I tried to recap this beast. Well I did something stupid by not reading the prior 1010 rebuilds and charged ahead and worked on the 054 board. I installed the transistors incorrectly (didn't download the data sheets) in order to determine what was E, C or B. So after installing the trans wrong, Q2 and Q3, I powered up the unit and was met with loud music and then magic smoke.:tears:
So started again by reading the 1010 threads and recapped all the boards this time using mattsd's and mtf's cap list/bom. So I get all the parts installed and go for the offset/idle. Somewhere along the line the wire from pin 13 on the 054 board to pin 11 on the protect board broke. So I recapped and installed new transistors in the protection board (all but Q7) the equalizer board, the tone and control board.
The diodes on the 054 were also checked after pulling one leg. All test good. I also replaced R11, R12, R20 and the rest were tested again by pulling one leg of the resistor.
Fast forward....
I just got done checking the resistors on the right 032 board, all are within 10% of spec and replaced most of the transistors except I have not done Q1, Q2, Q9, Q11, 12, or 3 but those were replaced once before right after the short appeared.
I pulled the output trans and checked them using EW's 6-way test and all are good.
So I am again looking for help in getting my First/Last 1010 up and running again with the experts on the forum. FYI, this my hobby not a business. I just got crazy buying the Pioneer receivers. As my title indicates First/Last one. Way too many (3 1010's)
When I fire the unit up on the dbt, Q1 on the 054 board starts to wisp smoke and the heatsink gets hot very quickly. So I shut the unit down to prevent any further damage. I tried to get some readings from the 054 board but with the wisps of smoke and the heatsink issue it is hard to keep it running to get the pin readings on any of the boards.
Where would I begin on this beast.
Thanks again to all who will guide me once more.
