Quiet around the PNW as it has been most days, When it does pickup its very late afternoon.

You can change up the heater wiring and use 6LF6 tubes its a pretty simple mod.

I have seen these with both 8950's and with 6LF6's. 6LF6's are half the price of 8950's $100 vs $50 EACH. I have 1 of each.

Well i love the old sweep tube amps, I collect them and s l o w l y repair them. My problem is after that i should sell them but for some reason they just end up on my shelves. It seems once they are cleaned up painted or whatever it takes to make them look and work good i just cant let them go...

60 bucks? for 8950 they are going for OVER $100 each!

I can tell you that over the last two weeks there have been 2 Palomar 310m for sale really cheap. Both were sold under $100. The only reason i watched them was maybe for spare parts to use in a Skipper 300 but found another way for its parts. Also last week Goodwill had a cheap one also. Good luck.

Here we again Here we are again, The Astroplane, Now that it has finally warmed up way up here in the PNW I have a tree climber that is ready to climb up and mount my antenna. I have been reading about using baluns. Now not being a antenna or RF engineer I have to ask questions here for...

I just ordered a box of 2 watt assorted resistors, I have 22ga solid wire is that large enough? If not is it safe to use two strands twisted together? The wire diameter on a similar size amp used 1mm diameter solid wire which is about 18ga.

that was my guess, again as always thank you!

Thank you, one last question what wattage should the 47 ohm resistor be? I am sure it will be more than the 1/4 and 1/2 watt ones i have in stock so i want to order the correct size. And as always thank you for the fantastic guidance. And i forgot to ask why are they used?

Hello all My newest project was to bring a Palomar Skipper back from the dead, I found the problems fixed it and even found a set 0f good 8950 tubes for it. However most tube amps that i have worked on they have had large resistors with wire wrapped around going to each plate cap and or little...

So let me see if i got this, IF i want to use the 6KN6 tubes in place of 6LF6's i want to make sure that it is the single version not the double version. And it is going to be a test as I found a source that i can by unused NOS tubes for under $15ea or good pulls for half of that. And for that...

Yes you are correct, the link that you listed is the one that i read and was talking about. Prefered Substitutes ........................6LF6, 6KD6, 6LX6, 6MH6 Substitutes ................................ 6JS6 6KN6, 6LB6, 6LR6 As you can see it shows Prefered and just substitutes and the 6KN6...

Hello, I have a couple of 1970's tube amps that i am slowly working thru and rebuilding. I have a Palomar Skipper 300 and a PAL 351BDX and they both use 6lf6 tubes. At first i was going to rewire them to use higher voltage tubes but then i was looking at the 6KN6 tubes and they do show as a...

Thank you, that's what i thought you meant,

Sorry i dont want this to sound mean,,,,as opposed to?

Hello I am trying to replace a variable cap. According to the schematic it calls for a 0-15pf. I have a spare amp of the same kind that at some point i will repair but for right now its for replacement parts. On the parts amp it has a E.F Johnson 167-2. When i look for a replacement the only one...

Looks like you will have to rotate them.

Hello all I am trying to restore a 12/74 PAL 351bdx and when i hook it up to a antenna there is no signal passing thru. If i follow the schematic it should run thru a few legs of a relay so my first thought is to spray it out real good. First a quick background the amp came out of a garage where...
