My Inspire 6L6 "Fire-Bottle" build slideshow. Came with a NOS Sylvania 6BX7 driver, a pair of Tung-Sol 6L6-G large bottle power tubes and a NOS RCA 5UG4 rectifier. Dennis also included a 6LS7 driver to try.

Stopped by his shop on Tues and he says he is at least three units behind. He's also making a new headphone amplifier and has been mumbling about building some quad monoblocks based on larger power tubes such as 6BQ5s, 6L6s/807s or even 6550s. You want to get in line, contact him through E Pray...I think if you wave enough money at him, he'll build you whatever you want....

Hard to believe he's "retired"! Great guy and superb equipment.
His seller page is the best way to contact him:

Rich,
Pleasure meeting you the other day. And as I'm sure you can tell, retired is only a state of mind with Mr. Had. He's been toying with taking over the space next to his, but he knows all too well that his "hobby" business will expand to engulf the available space.
I guess you've seen the pix of the 45 amp I left behind at Dennis' shop?
As I left it...
And for the benefit of others....
Gotta love the blue glow....
Up the skirts....
Here's what he did:
New proper coupling caps (looks like Kimber 0.22uF with a .022uf bypass)
Proper by=pass cap on auto bias
Copper/gold plated output posts
Gold Plated RCA input
******* Type 83 mercury vapor rectifier *********
Rear panel main power switch
Front panel stand-by operate switch (let the 83 warm up for a couple of minutes)
He also looked at the circuit and it's characteristics and changed the 6SN7 to a 6SL7as a better match to the circuit and coincidentally increased gain. I'm going to go over for a listen on Tues....
The best thing is that this amp will eventually make it back to my stable...:thmbsp: Having Dennis as a friend is a wonderful thing!The bigger news for fans of his gear is that he's already ordered the parts to make a 45 amp of his own, with all the improvements he's been refining as he continues his audio journey. Some of you may remember that he once built custom order 45 monoblocks as a Cary one off.
He says you can still get good new 45's from Sophia, so for fans of his work and of flea powered toob amps, you heard it here first.

That's a bold statement for a one eyed fat man.
Not sure you're going to hear many more statements from him....
As promised...
Here's the new amp. He's keeping this one for himself. 2 watts of sonic bliss....

Does Nichicon still make that vintage looking cap?

What tubes are you using? I have tried a lot of different tubes in mine, the tubes in the pic just happened to be what was in at the time.

I would love to have one of those in a 2A3
I went over to the shop yesterday to do some comparison listening between my amp and his. He was running 2A3s in it when I arrived. Said with those tubes it was putting out just over 3 WPC. Anyway, here's the shootout...
He had some other folks stop by listen, and he was very complimentary with his comparison, saying he wouldn't want to have to identify which was which while blindfolded. He's also got a new preamp that he really likes as well...
His wife thinks he's gone off the deep end, since boxes of tubes have started cluttering up his house as well. I'm afraid I have infected him with "Globe-itis" or "double digit delusions"
However, the difference in sound quality is really noticeable. The pre amp will run either 56s or 27s, and you can really tell when you go from 27s to 56s. I did try and get him to do the Uncle Festus bit for this picture, but he said that 120VAC wasn't going to cut it with a globe 45....

I received my Inspire 45 Fire Bottle Amplifier today. It sounds amazing, true single ended triode has a unique sound. I have been enjoying listening for over 2 hours. Dennis Had included a pair of vintage globe 45's, a pair of vintage coke bottle 45's, a vintage 5Z3 rectifier, a vintage 80 rectifier and a current Tung-Sol 6SL7GT tube. The extra tubes are for tube rolling. Dennis Had is great to buy an amp from.

New developments over at the Inspire shop...
Went over to Dennis' shop yesterday to finish up my new phono pre amp. Dennis and I got it up and running, and he ran it through these new 807 monoblocks....
He's running a 6SL7 up front with a regulated B+ supply. They had some impressive dynamics, and sounded great with the new phono pre. In fact Dennis liked it so much I left him the schematic and he was already ordering parts for his. He is going to use 6SL7s instead of 12AX7/7025s, mainly I'm suspecting because he likes the new Tung Sol 6SL7.
Bottom line is any of you looking for an Inspire phono pre amp, I think the wait will finally be over. Oh yeah, and I also saw him experimenting with an RF controlled remote volume pot for future use, most likely in a new version of a pre amp....:thmbsp:
