Well looks like the EL-509 is the replacement to try since mine has only 9 pins they should be the same..

Thanks for the reply,I noticed there are 2 types of the 8975 One is a 12 pin and the other is a 9 pin like mine..I just have one that is bad and The amp still produces 500 watts..Just cant find anything as far as data on this tube..

I have a Galaxy 800 that uses 8975 9 pin tubes and one is shot..Is there a drop in replacement for this tube?It has 0ne driving 2..Will a 6kg6 or pl509 drop in?Thanks..Hello anybody out there?

For sale or trade a nice wavetek 3007 Signal generator..Very well built and very accurate.Just let me know if your interested and what you have in mind.Have owner and service manual on cd as well.Thanks..As you can see it's built like a tank..

Oh yes..The difference in how quiet the Lincoln is..Now the lincoln is not as selective as far as adjacent signals on the 450.. But that is to be expected it was a 1300 dollar radio back in the day..But if you compare them side by side the lincoln has the upper hand on quietness and a bit more...

Anyone know if i can get the version 3 to cover the 12 meter band like the + Version?Thanks

Version 3 Not the plus..They said tonight on 10 meter it sounds better than my Ts-450 Makes me sad..lol

I know there have been some different views on this little radio from many different users..My thoughts are it's a Fantastic radio.Just got it in and i have compared it to 2 different rigs on the same antenna..A 2950dx and a kenwood ts-450s..I can state for a fact mine has a lower noise floor...

Hello gentlemen i am in need of the low voltage supply transformer 6.3v ac @ 2.8 amps ..and i think it also supply's the screen voltages as well...Can anyone here give me the exact specs of this part so i can try to locate a replacement...RF parts does not list any..Or someone that could rewind...

Can you send me a copy of the inffo you have on the digital rat shack wattmeter to n4dxxradio@gmail.com Thanks

Nope was not a hack job as one of the pins on the diode has zero solder and a huge blob next to it shorting out some resistors...And the diode was barley hanging sideways on the 3 pen pad..

Found the issue D90 was installed wrong ...It was sidways and when the machine at the factory soldered it it blobed some joints together and it was pulling the regulator voltage down..Wow what a mess!!I just traded for another one..Think i'll sell it..:)

Replaced both regulators...No joy,I am seeing only about 2.5v on the collector of both regulators...Puzzled

Thanks. I will get to the source ....and will update asap

The only way i can get the am power down is to drop the apc voltage and that in turn drops the ssb apc...hummm

Ok here is what i have found..I replaced the b827 No joy ...However if i run vr15 up to 6 volts i then can get vr 18 up to 12.5 But the radio key's 150 watts on am and i can't get it any lower...Wow at least i am learning and this radio has been this way from new..Hummm...according to the...

Just what i was thinking..will update asap

Well i may puke on this thing with the apc all the way up in ssb mode i can only get 9V Don't that duck your hat in the creek and am mode i see 1.5 volts with about 6 watts on the meter ...

They are all irf 520's Just a quick question could the apc voltage settings affect the gate voltage in any way?Just curious

Wow i can only get 2.9 volts on the gates on the main pcb all the way up!!!
