I need a Mckinley faceplace in good to excellent condition.
email me price and shipping. Here is a pic of my trashed face plate.

For some reason the RF driver bias is jacked up and I can barely bring it dowm to 60+ mA...but TX / RX seems to be woking good.

I was going to check the PA speaker audio but the radio has the Mod limiter switched On/Off threw the PA/CB switch. While looking into a remap of the PA switch and to put the Mod limiter back to original I found a bad solder joint at the PLL. Although it did not appear to be the real problem either?...

I have tried various Mics Including: Astatic D104 Silver Eagle & D104-M6B as well as Stock Cobra and President Mic's. I did not know that the TA 7222P was not used for SSB mode, so that info will help narrow it down (SSB is weak too)...I am still concerned about the low voltage on Pins 5 & 6...

Cobra 142 GTL Weak Mod Ok AM Power. SSB is weak also. Tried re-align as per SAM's with two tone signal generator...no real gain. Replaced Finals...no change...replace IC4 AF Output TA 7222P...no change. IC4 voltage's not correct! PIN 2 = High @ 7+ volt should be 2.95v PIN 5 = Low @ 1.1v should be 1....

I replaced both Finals (Motorola MRF454's) and this amp has one adjustable potentiometer. What would be the purpose of this pot and how should this pot be adjusted???
Also I would like to make this amp SSB compatible...what can I do to achieve this?
