I hope your frigid toes didn't trick you into signing that check yet. Furnace repair guy has you over a knowledege barrel. He will pay $500 for the unit and give you the high hard one. You being a handy sort of fellow, should motivate you to do some internet research based on the boiler plate information on your existing unit. You could save $1,500 if you do your homework. The easy way out requires Vasoline and no new amps for a while. Break out the craftsman tools and make momma happy enough to give you that birthday treat early. Email me with questions.

Ive got four repairs backed up, two personal projects, and a couple tolex jobs. Between family, chores, practice, gigs, jams, teaching, who has time to rule the world?
Just finished this up not too long ago. http://home.comcast.net/~psymonds/6SN7amp.htm
You can listen to the clips at your own risk, as I am not much of a player. If you choose to listen, the clipping you hear is the recording, not the amp. I finally figured out I can use a 6AQ7 for the PI and scored a half dozen ("used tested good" LOL) on eBay for $8.50 shipped. This lets me keep the more expensive 6SL7 for an application where I need both triodes. I'll be rewiring that socket.
I just received a chassis for an Eicor Model 15 tape recorder, including tubes, another eBay special, $21 shipped. I got the SAMS Photofact from the library (free to cardholders), and determined that the circuit wouldn't be particularly good for a guitar amp; too much stuff to rip out. So, I'm presently stripping it for parts. It seems the PT and OT will make a perfectly fine Champ. The PT is 550VCT and it came with a perfectly good looking 6X5GT. The OT is 4K6 to 3.2 ohm, which I make out is roughly the same as 5K to 4 ohm. There is a mystery tap on the OT for which I haven't determined the impedance. It is all octal. I'm considering a 5F1 or 5F2-ish thing. I expect to build it for under $50 and this one is likely to end up for sale on eBay if I can bring myself to part with it. Just having a bit of fun with it.
Anyone want a pair of 6SJ7's? I have no idea what can be done with them. How about the tape recorder head? Or the erase interlock?
After band stuff, I noodled inside one of mine, did a superlead varient with
master vol. The tone is as expected, might be a good chance to try a different master setup.
Ill peg it tomorrow and see what come of it. Another fairly simple pre, and widely accepted by many, The next jam will be fun.
Finished the Princeton clone yesterday. Sounds pretty good. I added a boost switch on the cathode cap on V1a. Also added a presence control. Now to have a combo enclosure built. Next amp? Maybe I will go ahead and finish the 18 watt Lite IIb I started two months ago!
My name is Marlon and I am an amp-aholic.
I'm thinking along the lines fo building a couple 5E3s, that way maybe I'll get to keep one. I have a bunch of those light green Cornell-Dubilier caps, mostly .1s but I have one solitary .022.. That says Tweed Deluxe to me. If I had more .022s I'd build a tweed Pro or Super. Vintage .022s, that is... I have a ton of Black Beauty .022s, but where are the Black Beauty .1s? Well, I was digging for a document and I came upon a whole box full of them I'd put aside! The tweed Super is getting Black Beauties.
I have salvaged Schumacher iron with 1960 codes, not exactly Triad but the PT is a straight drop-in to a tweed Deluxe chassis. Vintage caps, vintage iron...
It's looking like two Deluxes, one with Spragues and modern iron, one with vintage cpas and vintage iron. New electrolytics either way, momma didn't raise no dummy...
2 amp projects in progress...
one (normal chan only) bf twin, i built from the scratch. still tweaking on the
preamp to get it tighter. it should become the perfect clean amp some day.
a bf oriented amp, which i converted to el34 use. the preamp is a little
hotter, but i'm also working on this to get the crunch i'd like. it was originally
a engl jive, failed to become a tw and tried to be a 5e3 in between (worked,
but didn't sound right).
working today towards finishing a small extension cab, black tolex, fender wrap,
magnavox gold grill cloth, 10" driver. Got another four repairs in yesterday
and need to turn them around before the end of the week, If I'm
not careful thing will begin to look like work.
3 amps in progress: a straight Rocket clone, a Hammond organ amp that will go in a Leslie cab (for guitar), and a Baldwin organ amp that I'm hoping to turn into a 6V6 Express.
Just finished a Tweed Deluxe 5C3 (all octal) built into a Grommes monoblock.
Have (2) 50's PA amps-one a Lafayette with 4 Loctal preamps, a 6V6 pi, a pair of 6L6's. Powered with a 5U4G. I replaced the filter caps and will go ahead with the rest of the caps. It has too much hiss and I suspect those old wax caps are the culprit.
The other is a Masco with a 5V4 rectifier (can I use a 5U4...or a 5Y3?), 2x6L6, 6SC7's, and a 6SJ7.
Baldwin organ amp...don't know what I'll do with it.
Another Cygnus SEL-I have all the parts-just need time.
I am waiting (almost 6 weeks now) for delivery of a BN 18 watt lite IIb kit. I am thinking it will get a VVR and post PI master too. If I knew it would take this long to get I would have scratch built it. Meanwhile I have been eyeing my already hacked up '72 Twin for a Dumble conversion. The thing I really want to do, if I can ever get started on it is a TW variant, but then I will have to get a 4x12 box to go with it... . At the moment I am just tweaking my existing D clone for a matching THD style 2x12 cab I just had built.

I'd pick up an AB763 circuit board set and put that Twin back to Twin specs. I'm thinking of keeping a couple rental amps on hand, a Twin is always good to have.
A Brown Note D'Lite gets you in the Dumble zone. Tell Moss to ship it with your Lite II...

I thought of building a D-lite at one time but I already have one D clone amp and wanted to try something a bit different, hence the 18watter. Also I had a friend who was possibly going to buy this amp after I built it, but since it is taking so long to get the kit, he has settled on another amp instead.
Meanwhile, the Twin just sits there. They are good amps to rent and I used to rent this one out some, but the music scene has dropped off a lot around here and I am not as connected as I used to be when I did sound and gigged more. Seems like you can hardly give Twins away lately. Personally, I am more interested in lower wattage amps than I used to be but that Twin got plenty of use in the day...

Yeah, a good Twin brings around $500. Weird. They may be like old tweed amps, you couldn't give those things away in 1980. Look at them now...
