Hi all,
Just got the first Stryker ever on my desk. It's the 440hp version. This thang was a mess, po old radio...
1st, someone tried to install a speech processor module and used the wrong wires. They used the orange and yellow wires leading to the external frequency counter port, hahaha.... That's the reason they never got the module to work.
2nd, they sniped the electrical ground from the echo board.
3rd, they removed tr32, tr53 and clipped r249.
4th, they volted the final back on the regulator with a resistor/diode combo.
5th, they ruined the mic socket board.
6th, they pinched a few wires between the echo board and chassis.
After fixing all that mess, I found the output to be only 35w max on a peak reading meter. I thought these radios were made to do more than that. It has all 3 mosfets installed, but I think they weakened the passthrough regulator (which they had the volt mod on) and it got extremely hot within seconds of keying up.
Gonna replace the 2sb684 passthrough with a tip36c, replace the 1819 AF regulator with a 2sa1012-y.
I have noticed the gate voltage for the driver is around 2.75v, the first final mosfet gate is 2.40v and the last final mosfet gate is 4.19v. But I only see 1 bias adjustment. What gives?
Anyone have the alignment info on these radios.
Thank you in advance...
