    Well, let's see you could start at the pre-driver and make sure you have 27megs being delivered to the base of the pre-driver transistor. If not then you should check the transmit mixer stage and make sure your oscillator frequencies are present if they are but you have no 27 megs at the FET...

    What caused L39 to burn up ?

    Well, the best I can remember L39 is the choke thru which the collector current for the final is fed. So if the Final shorted from collector to emitter it's plausible that could get the choke pretty warm but a proper fuse in the radio should have prevented that, "I think" but maybe not it is...

    Cobra 25 LTD Classic, no voltage change tuning

    Do you have schematics and alignment info? No disrespect intended but what is your level of understanding of how this radio or any radio works? And then we can figure out what we need to do to guide through the process. not every part of in radio will necessarily have a voltage or signal that...

    BBI amps, anyone heard of them?

    Do you mean back when you could build a brand new home for less than $30 or when gas was less than 30 cents a gallon or cigarettes were 25 cents a pack or you could buy a brand new VW Bug for $1850.00 Hamburgers with a drink & fries for $1 or when a Phone in the home cost $8 a month or when your...

    Pill factory

    I understand the above, but one of the hallmarks of the repair industry "at least where CB amps is concerned" I get as many as 150 amps a year to repair and turn away that many, and in my world the 2SC2879's the 2890's, the SD1446's the MRF455's, etc are KING!. We can discuss till the cows come...

    Oscilloscope ?

    And now I will agree right back as I use my Hitachi 100mhz for tracking modulated waveforms as it is in line all the time but I do like the Rigol for trouble-shooting stages at the component level

    Oscilloscope ?

    Well if the counter is accurate Yes and if you are talking about the alignment of Offset osc. it should be pretty accurate. That being said I use a Rigol and I had to do some alignment mods myself to have it display accurate results. I use my Rigol a lot and don't have any real complaints.

    eBay new payment system

    It's not a scam but it is a pain in the Arse. What eBay has done is made it better for them they get their money right away and eBay pays PayPal percentage if you noticed your percentage went from 10% to 12.75% and then you are required to ship right away and then 3 to 5 days later you will get...
