Hey,
I have this old (1997) 142GTL. It got it modded every possible way I think P.O. It has low power so I lifted the legs of the 1306 and 1307. The 1306 tested bad. I had a 1969 and put it in but now I have ZERO bias current. Previous owner had the voltage turned up to over 15 I backed that down to mid 13's.
I have a dvm o-scope and pace 5403a meter so I can't do everything. I have a sig. gen. OTW. No freq counter so far. So any where I can test to narrow it down? Modulation on the meter is good but power out is zero. It was just very low ( under a watt ) until I swapped in the 1969.
TIA!!
