thats a damn lieif the dead key is above a watt and a half neither one will work.

I agree I have a Palomar 450hd now in my mobile I'm running it with it's own battery in the trunk my rci ranger 2950 DX is running from the AGM battery in the front ran all new 8 gauge wiring good ground ,on low it gives 150 with deadkey of 2 watts,on medium 225, but when I put it on hi it won't go past 250. Can't seem to figure out why.also it's iny mobile but still I should be getting at least 325 to 350 on hiI'm just not seeing that. I have had Rat Shack radio's that would swing maybe 5 watts from a 3 watt dead key. Any amplifier I ran it into would not even hit half the normal peak wattage. There is no way a pep wattage or 3 will drive a Palomar 4 pill to 360 watts.
IS THIS WHAT YOUR AMP LOOKS LIKE ?? IF IT IS, IT'S A KEEPER .Can you post a picture of the board in the Amp?I have an early palomar TX400...
Have no clue what the pills are, never heard of them, they are Ssm RF85's BUT I can say from my galaxy 99v, with a 3 watt dead key in, and a 40 watt PEP, im seeing 500-540 on 3 different meters, and it takes a good 1/2 hr of ratchetjawin to start feeling much heat from the sink.
On sideband, same input, it kisses 800+
I did speak to one guy who had one of these exact amps in the day. He said that he used to know what the pills cross referenced to but now cant remeber
He said that he did remeber the pills were 150 watt pills though,so the output makes sense
Yep thats exactly it, less the fan kit, and ill tell you what , it frickin rocks.RF power transistors ( 85, 100, 120) were mil spec devices made back in the late 70s - early 80s. Like Timex watches, " will take a lickin' and keep on tickin'." That TX400 is probably not a Palomar, but a TX amp made by Steve Canfield back in the day.

I also agree with the 80-90 watt dead-key out of the amp. Isn't 25 watts per pill the formula?I ran across a old sales flyer for that amp today Says Boomer, but it is the same amp
400
4 sd 1446 transistors
4-13 watts input power 300 watts output power
I agree with 9c1 about the 80-90 watt dead key.
They list the 600, 1 1446 driving 4 1446`s @
input power 1-4 watts 400 watts output power

4x1446?I also agree with the 80-90 watt dead-key out of the amp. Isn't 25 watts per pill the formula?
NCA Gunsmith -4x1446?
this is a 5 pill.....so would the driver also be a 1446?
regardless of what pills are in it, this thing frickin rocks bigtime.
Good to know.Y
NCA Gunsmith -
RF POWER TRANSISTOR Co. (no longer in business) manufactured the RF- series of transistors that Steve used in his amps. He told me he found them at a surplus place. An overrun from a Govt mil-spec order. Sadly, - no longer available . 1446s aren't subs. Not even close.
I have three TX amps: TX250, TX600, and a TX800. My 600 has a RF110 driver and 4 - RF120s. Will do 750 watts peak all day long.
TX amps were the BEST ever made. Steve was an amplifier genius. Like you said his amps "frickin rocks bigtime." I got my 600 in '78, and after 50+ years of hard use still going strong. Bulletproof. TXs seldom come up for sale anymore. If I see one, I grab it - working or not. Just for the parts. 73.

Yes, wattage rating- wise they do cross. But being to withstand being overdriven or over-voltaged the RF pills are in a class by themselvesok...found out quite a bit of info by calling RF parts.
that RF85 tansistor actuallyu cross references to motorola SRF3795 80W pills. also crosses with the MRF454 motorola.
That's what the guy at aRF parts said too. My big thing was just to find out what the crossover was just in CASE of a future mishap, id be able to order a new set and install themYes, wattage rating- wise they do cross. But being to withstand being overdriven or over-voltaged the RF pills are in a class by themselves
