Your example is not a measure of a an amplifier but a system that has other frequency determining components. You also are mixing or combining the products of RF IF and AF in the receiver. But a simp
I have some NEW 124.0311.100 11 Pin Johnson sockets for 3CX800A7 , 8072 ,8122 and 8874 tubes. I will sell them for $19 each plus $6 for postage for any quantity. Compare this to $40 or more that comm
I am sending this again. Either something went wrong with my email service or the message did not go to everyone on the list. I did not even receive a copy of it my self. If you emailed about the soc
It is amazing that so few hams have not been eliminated by "Natural Selection" doing stupid stuff. I know I have done my share of hazardous HV RF experiments during my younger years. I am more carefu
Maybe so but he probably is not driving it 155 thru the neighborhood over-reving the engine throwing bits and pieces of connecting rods and crank shaft that become shrapnel injuring the neighborhood
Here we go again.... CB use of linear amplifiers is illegal... And all you need to do is look at my past email to get my opinion. No sense in going over it again and again.. There are many negative a
The whole point is legal operations. Very few ham or for that matter NO CB operator needs to be concerned with filament currents over 30Amps. You don't need more than 30 Amps filament current in an a
Unfortunately there are a number of hams that came up thru the CB ranks that are active freebanders. I can appreciate your efforts to rid the list of the illegal radio operators but you just can't. T
I have been selling ,a few at a time , insulators (1"dia. x 6"), rectifier stacks, tube sockets and other stuff on amps. However, it is time that I put them on E-bay to move it along. A number of ite
A current limiting transformer is the type used in your microwave oven. It has magnetic shunts between the primary and secondary such that if the secondary current exceeds a limit the flux is diverte
If you look at his past sales he has been selling CB linears. One listed as a hot plate???? <http://cgi6.ebay.com/ws/eBayISAPI.dll?MfcISAPICommand=ViewListedItems&userid=colt20&include=0&since=30&sor
An 807 would probably oscillate cathode driven due to the fact that the suppressor (beam forming plates) are connected to the cathode internally thus providing a lot of plate to cathode capacitance.
In grounded grid a 304TL will provide a power gain of about 4.5. 200 watts drive for 900 watts output. I have considered 1 304tl driving 2 all in grounded grid. I have a lot of 304tls. 73 Bill wa4lav
It only means that 29MHz was heating up the resistors and no more. Most likely because circulating current was not only flowing thru the Plate tuning capacitor but also thru the plate to ground capac
