Cobra 29 High Power mod with 2sc1969 transistor

[Chris Millas]

I installed an authentic 2sc1969 final in my 29 and left the stock driver. It produces about 20-23 watts.and has been running this way for years. I personally prefer the 1969 over any other final for a 29. It works well and sounds good if the radio is tuned correctly.

Ok back to another question that was raised here earlier maybe 3 pages back has anyone tried the new 2030+ or the hg1969+ I'm here there is one of those out now as well from hg.

I've been playing with the new HG2312s inside of the 29 chassis. Leaving all other components in the radio with the expection of changing a couple caps. C71 and the 1000uF south nearest audio transformer to a 3300uF (16-25v) after a tune with clean waveform we see it produce 28-34s peak depending on the radio. Each will slightly vary. Of course if it's a newer 29 chassis we need to remember to remove a turn off the coil of L14.

But I hope to repost a thread shortly after some further experimentation is done. And we have a complete guide for installation.
