Which one is better overall performance ?? 1st,2nd Gen. 2950 ?? Or 2950dx with Green and the new Black face design ?? ( Note Blk Face has Mosfet Finals )
My 2950DX ( green display) has dual 2sc2312`s in it with a 2166 driver.
And A Bill Good designed MOSFET front end.

I could have sworn it was irf520
You probably looked at one of the later production runs after they switched to IRF 520 finals and the TDA 2003 Audio Chip.
The Early Serial numbers all used 2sc 2312`s and the original TA7222AP Audio Chip. I am to lazy to go un-mount the radio from my pickup and take a picture.
Here is the Schemo from Ranger on the early ones.

My 6900 F25 runs dual 2312`s as well.
I do not remember seeing one with 1969`s but it is possible.

I have the Ranger2950Dx 3 gen. and I hear the finals are different from the original 2950 1st gen.,this will sound like a Stupid question but what is the difference, more power,less,made better and lasts longer??? Just curious.........................I just picked up a 2950dx used and it has dual 1969 finals. Only issue this one has is the audio coming through the speaker or speaker jack on rear sounds garbled. Any ideas?
Other than that everything works and transmits great. the board is a EPT695014B
Incoming Region Produces X3 Solar Flare |

Another major solar flare, but this time from an active region just beginning to turn into view off the east limb. It is possible that the group responsible is old AR 3654 from the previous rotation. The latest flare, an X2.99 event just peaked at 14:38 UTC (May 15). Stay tuned |
