OK that explains why R1 burned up.
Q8 is shorted as well.
Do you have a replacement for Q8?

You r genius! I'm afraid I'm not! I have to order it!

 

I have 2 mpsa29

 

Two new MPSA29, that have not been used?
Not totally positive Q8 is defective as of right now. There is another test to proved definitively

one is the one I did replace (i take out soon after blowing R1 and put back the original) the other is new

I tested it and from one side the current flow but not on the other side, so I think they good

 

Most likely they are both defective now because Q8 is probably also defective
You can check the MPSA29 with the Diode function following my instructions when you are ready.

i'm ready

 

OK give me a minute

 

First want to test the transistor you have on hand, not the one installed.
Using the Diode function connect the positive lead to the base and get reading from the base to emitter and base to collector.

is what i have done before to test it. do you wont the reading? other wise they are ok

 

Yes I need the readings and also read from emitter to collector please.

I have exactly the same reading in both the new and the old

 

That does not tell me if they are good or not, what are the readings please?

 

I have exactly the same reading in both the new and the old

C:726 E:1.300 on both

 

And the reading from emitter to collector?

 

C:726 E:1.300 on both

when i refer to the old, I mean the new, which has been installed and remove soon after

And the reading from emitter to collector?

no reading

 

None of this make sense from the voltage readings previously.
Do the same test on Q8, you don't have to remove it from the board just make sure the power is OFF.

the voltmeter is beeping

when you said check the voltage, do you mean change the meter from diode to volts?
