Sorry! I thought you meant phono stage in the preamp. But, still don't know if he's looking at phono pre pieces. I haven't seen any in his ebay listings since I've been following. Best to ask him directly I think.

Welcome Bob! Cool, you do live pretty close by....and you build your own amps!! Awesome!! :music:

I've got my amp set up with a volume pot so you can plug whatever direct sans a TT but I've got a portable battery powered phono preamp I could tote along easily as well ifn's you like vinyl.

Cheers,

Yeah we'll have to get together sometime maybe a couple of times. I'd love to check out your 105 db horn loaded speakers, you could probably run them with 2 watts. Then maybe when I get my Inspire amp, you could bring your amp over to my place and we could compare the KT-88 to the KT-150 in both amps.
I'll have to try to figure out how to PM you offline with contact info.

Oh yeah, I do vinyl, that's why I have a Cary SLP-98P preamp, with onboard phono stage. We could also try running your amp direct with your battery operated phono preamp, and then through my Cary preamp. All these tests could take weeks! :whistle:

Cheers,

Speakers are Electro Voice Sentry III I rebuilt them - crossovers re-foam etc. Yes I would love to do a comparison side by side. I'm getting ready to build another amp specific for the KT150 and I was looking for pictures of Dennis Had's amp you bought for his wire layout which brought me here. Dennis does excellent work you should be very happy with your amp. Did he ship it out yet or is he running it in for you first?

Cheers,
Bob

He's still building it Bob, I just ordered it on Sunday. I'm sure ordering the custom chassis and faceplate will take a little time. I have no ETA on the amp yet, but I'm guessing it's a couple of weeks out.

Cheers,
John

Peter, what difference did you notice between running with the 5AR4 rectifier and the 274B? The 274B looks much bigger, strange about the lower output. I've been doing some reading about these regulators in general, and it seems that most seem to favor the 5AR4 because it's slow start ability protects the other tubes in the circuit better??
The 274B does look cooler though. :roots:

I've read the same thing about the 5AR4, but I'm sure that he designed to work properly either way.

For those that might be interested, Dennis is working on a 6SL7/6SN7/5AR4 phono-preamp for MM/MC that should be finished by the end of the summer.

Just got some pics tonight from Dennis on the progress of my new KT88 amp. He says he likes the color so much that he's gonna have another one made next week so he can keep one in his listening room. :thumbsup:

Very nice!!
Cannot decide if I want to pick up a Cary SLP 98 or one of Dennis' new preamps.
