Tubes Well dam it got 23js6 for tubes...:oops:

tuning My unit has a toggle switch besdie the driver tube....Does this disable it???:huh: If you look at the driver tube you can see the top of the toggle switch to the left.

Can't find much on it. 1 driveing 4 20lf6...Need to know setup process???Also dead key. and modulation. Thanks in advance... Just wanted to know before <can not stand it> I have uploade 2 pictures below.

Just aquired a Amp Supply Co LK550 HF amplifier.Has 3 of the 500z.Gonna let it loaf at 1500 watts only. What i'm curious about is that my coax run is like 150 feet to the top of the beam.LMR 500?????This will be my longest coax run ever. Thanks for any help.<can not stand it>

mfj-259 got it for 50.00 at estate sale..<gotproof>

mfj-259 I can get it to power on with two batteries. The red power light comes on and zeros show across the screen.That is all it will do any ideas???:)

Anyone know the transistor locations are for the driver and final rf out on this model?:thumbup1:

Matching Stub I converted mine...The Cap was toast... Got my SWR down to almost nothing... page 11 in owners manual. rg-58 approx 9 foot long...I used rg-8. After verifying swr and some tests...Cranked up the wattage. :drool:

Freeze Spray Gets really cold.....Turn can upside down and will freeze....Good for heat int problems...**Jump_im**Course its all gone by now :tt2:

<More audio> Converted my 2nd gen useing the capacitor/coil to the stub cable version. This corrects high swr on omni or all dircetional. If you run more than 50 watts on this model it will fry the omni circuit(2nd gen) I cut off 9 foot 1 inch of rg-8.Soldered to board parallel to old...

transformer I have the 300 z... Check this out... Palomar Electronics Corp. Model 300A :biggrin:

1/4 wave ? When not active, the element lengths are made to appear longer by the quarter wave coax sections. If the coax does not add the correct amount of inductance, the elements will not act as reflectors and the pattern will be an oval shape with equal gain front and back. Computer...

super scanner Hi jas what did you ever to with antenna?:confused1:

tube amp master :thumbup:You need to get up with Danny Muckelroy in Conway South Carolina....He is the master of tube amps.... Sometimes you can find him on channel 1 in Conway area.:thumbup: Go's by TURBO

I notice its uses 2 2sc1096...Can i go back with 2 2sc1969??:confused1:

HI ALL I'M FORWARDING THIS FROM SLUGGO.... THIS REALLY ENHANCES THE AUDIO.. Look at the circuit board and locate R220. It is a 220 ohm resistor located between TR23 and VR7. Notice that it is installed in a location marked D23 on the board. Remove this resistor and replace it with a 1N914...

trc 458 restore Got about 3 hours on it.... Thanks for the tip sluggo....I'll do it..... :thumbup:

Found it! :thumbup:Open trace on main board...Can't see with the eye.:thumbup:

Got another 458 The rf outputs were gone....Replaced with new ones...driver and final. When i key it up i have no output.Relay clicks and freq counter shows 27.965 or channel 1. Powered with ext 12 volt supply when keyed shows 1.4 amps. Which should be normal.....Figureing something before...
