Phred sent me some pix of the new maul I thought i'd share. Gonna show some of them to the movers so they know how to deal with this 1300 pound bundle of joy. Others I've massaged a bit and wanted to post here.

IMHO, this shore is a purty transmitter.  Cheesy  No blowers = no blower noise.

you cant have too many meters on a radio transmitter. It's impossible.

What a beautiful rig Derbmeister.  Raytheon is my favorite 'trademark' (used to work for them, indirectly, Sesimic Service Corp., div. of Ray. out at the Nevada NTS)

... & would you look at that name plate.  Just gorgeous!

Man, I"m envious.

Oh, BTW, you name all your rigs 'Maul.'    Is this Maul 1, 2 or 3?  Grin

Maybe "RayBoy" or somesuch?

Yea, why were they so stingy with the meters?
If it was well built, they would have meters for filiment voltage and current for EACH tube!

Nothing better than a rig without any fans or blowers!

Derb,

Maybe it was mentioned in another thread, but is this the old N3WWL "Lowest Voice in America" transmitter?

If so, it sounded FB.    Was it converted to 75 / 40M too? 

If not, a couple of Vac variables and some work should get it on 160 - 40M too...

Derb,

What a beautiful transmitter, both in terms of condition and of style! If any manufacturer ever overbuilt an AM BC rig, it was Raytheon or Westinghouse. Take a look at a photo of a Westinghouse 50 KW AM BC rig sometime (I think the model was a 50HH or something) and you'll see what I mean; most impressive.

That is one hell of a clean machine. Use it and enjoy it!

73,

maul is just a ghetto term for keying the rig - the "maul" is the carrier.  Cool

slopbuckets be teh wood. illustrated as shown. That wood on that stump is a ignorant AM hatin slopbucket.

Tom: yes, this is the "lowest price in America" transmitter.  Cheesy  It's good to go on 160 or 75.

Derb,
Best of luck with the transmitter.  I have been on the other side of the QSO with Jay, N3WWL many times when he had the beast on the air.   It should be pretty much of a plug and play piece of gear.  Its been interesting to follow it around as it has had quite a few homes.  Are you going to use it remote or will it be in the Ham Shack?  I remember when Jay had camera's on it for remote operation.  When is it expected to arrive?
Regards,
Joe, W3GMS

It's expected to arrive as soon as I can pay Phred for it in full and afford to pay some professional movers to get it here!!  Cheesy
 
I'm gonna get it here as fast as a I can, but thats still probably not for a while. I'm describing it as a birthday present to myself and thats on April 25th. I'm thinking it will be here before then though. But a large part of that is gonna be how much I have to pay to get it moved.

It will be in the ham shack. I'll probably wind up sitting right next to it. That's where the 220 plug is.

This is incredible news, Derb! It'll be great to hear the 1400 pound 'baby' Raytheon back on the air making some sweet audio. Like Joe & Tom, I remember many a contact with Jay when he had it on the air and even did my best to talk him into keeping it when the time came to send it to a new home. It was working and sounding fab the last time I heard it, so you should have an easy time of it (once it's set up, of course).

BTW, heard you on 75 last night with WB4IUY who is maybe 10-15 miles ESE of here as the crow flies. You were strapping into NC in fine shape. The RA-250 will make you one of the big munkeys down this way!

Derb, I heard your rock-crusher signal here in HotLanta yesterday evening, I think you were in QSO with W9LRS and later with KA0ARA.  Your signal was the strongest of the three here.  Fine sounding rig!

Can't wait to hear that Raytheon STRAPPING!

Sure looks nice Derb. Enjoy.

Do you know who manufactured those beige colored xfmrs?

I have a pair of chokes from a Raytheon RA-5 and would like to know the spec.

That thar rig is a beauty, Derb. You have every right to out-smug the Flex guys now.  Wink I actually found a clip of Jay's RA-250 transmitter (yup, it's the same one) on wikipedia...

Well Derb,
Sounds like you will have a nice source of shack heat. Now that you have a dozen rigs to build there will not be much space to heat.

yah, I will have to beggarz to wifey for more.  Tongue

I do not know who made the iron for Raytheon. Let me look in the  manual and see if I can get anything from the part numbers.

Dave: the manual states that the supplier of all the iron in the rig is Raytheon, except for the audio inpoot transformer which they list as UTC. Raytheon surely could have made that iron back in the day.

The quality of Raytheon transmitters of that period is unbelievable. The cabinet steel is probably twice as thick as any other, and they used a cabinet-within-a-cabinet design. The different chassis as seen in the photos are actually hung around the insides and top of the inner cabinet, allowing easy access for servicing, cleaning, etc. Even the trim is top quality.

Derb, I'm checking into some spare iron left behind when I removed the RA-1000 a few years back. If you're interested, I can let you know what, if any, is still available. From the pics, it looks like some of it is interchangeable between the two.
