    Dynamo Gold 150 (dual MRF455) Schematic needed

    I have seen someone post this model before, so it cannot be a totally obscure amp. I feel it is a classic dual MRF455 type amp, so really any schematic with that transistor set will probably be close enough. This amp has no output, the MRF455's seem ok. Nothing is visually burnt. It was...

    Alan 9001 final problem

    Hi, Sorry to hear of your troubles. First of all, If your going to try to use a 2SC1969, for a final, you MUST use the Insulator. The Mounting tab CANNOT be grounded. In the 2SC1969 the mounting tab is the Collector, in the MRF477 the mounting tab is the Emitter. You probably will not...

    HR2510 clicking from microphone

    Hi, Nope never run across that one before.. Has this radio been modified to remove Talkback? If so I would check the mod. If not, I would Check the 470uf inductors mounted on the Mic jack board, see if they are burnt. Other than that, Check for voltage on the Mic jack pins, and...

    2510 power seems to be dropping. Final or driver?

    HI, It is normal to see a lower PEP when adding an insulator. The only explanation I have for it, is that with the insulator, you are no longer suceptable to the "RF Feedback Ground Loop" Problem, which I believe may have been causing 'false' PEP readings (higher than Actual) due to the...

    Lincoln TX problem

    Hello, I hope I can shed a little light on this. It is possible your TX troubles are caused by a bad Capacitor. There are a couple in the radio that are low rated. 10v instead of 16v or 35v capacitors. They can go from slight pwr surges or from 'Old Age' because they are in circuits...

    Lincoln S-meter

    Hello, What is the output power of the radio on AM and SSB? Can you check the RF Power meter when keyed into a Dummy load? Does it go all the way up? Does the SWR meter CAL adjust? What is your SWR on your antenna (using an external and the internal meter)? Roger </p>
