Personally I think that way of doing a dual final is crap. If done correctly with just replacing the finals to IRF520 you can easily get 40-60. If you replace the driver with a FET you can always get 60 out of it if you build it right. I am not a big fan of the EKL versions of the final...
I am fortunate enough to have 3 of the produced boards. There is no way I would ever have enough time to put into handwiring one. There are quite a few handwired ones out there though that are just as good. I am kind of surprised there has not been a thread about the mod prior to now. I have...
If I am not mistaken, several of these radios have been sold for nearly $700 on EBay. I think that typically they probably average $400-$450. They are alot of work to handwire, there is a group member that makes a pcb and programs the chips and sells kits, but I think recently he stopped doing...
This is not a 99 kit! There is information on the site about the 99 kit but this mod is a whole lot cleaner than a 99 kit. This mod gives you a 3 digit readout in the stock area and goes from -79 below channel 1 up to 108 above channel 1 with no Alpha skips etc. If you are on 3A it says that...
I just want to know if the removal of some transistor enables high power is necessary to get the 30 watts out of this rig. I have ran the TX strip and tunes for maximum output and can only get it to do 18watts PEP. I saw somewhere where you pull some transistor to enable the high power. What...
That is a very nice radio. Why do people pay that and more for the Gold Cobra 29? Nothing special, rare of course, but still an AM 40 channel radio. I have had people come in and drop a load on a radio I would consider outdated and junk because....."It was the first radio I ever owned" The...
I have a buy it now on ebay for $7. I use the link to the auction so fourm members can see the pictures. Yet the price to forum members is $6. Does anyone see an issue with this?
All I get is a single 0. I did change the diode and I also thought 10 volt blues. None of the above fixed it. I was kind of afraid that the Chip was blown.
I need an old style freq. counter module for an old Galaxy 88. Ive seen these in Old Galaxy IIs, some Old Couriers, some old Nortstars etc. Its the big one I need to light the common cathode LEDs.
I could do a mosfet upgrade in a Cobra 29 and you would never be able to tell the difference from the one done with the 1969. Hundreds done....NO audio complaints!

Ive been doing this for quite some time. Thanks for the info on dropping the coils. Ive got em doing another 10 watts now. 55 w PEP.
I noticed that you mentioned you dont have to use a matched pair of transistors....I dont know about that. I have found that all IRF520s are...
It has a single 2312.
Geez, Im gettin in here kinda late, I have to edit this a bit as alot of it has been stated already.
For talkback there is a switch on the back of the stock mic. Most of these I sold were used with an aftermarket mic. What I did was clip the jumper [(attached to the...
