Forgot to elaborate the Quad system.It is actually a tri-amp Quad system, below 100Hz is the Supravox 15in Field coil in open baffle, then it's a Stacked Quad ,and about 5Khz there were 5 RTR ESL cell. I did try the 6C33C amp in a single pair Quad by...

Dear Roman and all... also unrequested/unsolicited, MUST give my opinion on the above... I had to translate my 2,3 meters from my Gotorama speakers system, and obtained 7,6 or so feet... it's angled 110° in front of my head, placed on 5,3 meters long...

I note English Mfgrs tried low power ribbon Midrange horns in the 50's (Decca, Kelly & Quad also made one!).These were probably inspired by the hi pwr prewar? Klangfilm ribbon horn (would like to hear one of those!) But, after Peter Walker moved ...

[quote user="KOTriode"] Without regulation, this amp would not work correctly due to its design: DC coupled and fixed bias. The high transconductance will make the bias current varied as much as 50-100ma due power line fluctuation without the reg...

The preamp has the classic tube regulated power supply using 5R4, 6AS7, 6SJ7. It is transformer coupled output and has no capacitor in the signal chain, the gain is about 8db, so it is not a buffer. For convenience, it does has a remote control. It i...

At CES there were Viagra-junkie sized power cords everywhere for $5000. Around our room were $10k and $20k speakers that sounded like a wet jukebox. It was the land of delusion.Value per topology is one way to measure but let's instead start with a p...

Cat:First off, the Silbatone Aporia is $30k/pr not 100k. You could do 6 speaker surround with Aporia for well under $100k. Hope you feel better now."So what," I say. $30k is already too much for my pocket. I am on a fellowship this year and cheapskat...

First, Adrian, Thanks for your feedback on the newer designed 2A3 tubes... very interesting. I've looked at all 3 of these brands before but have not as of yet purchased any (I have a large collection of 45 and 2A3 of various NOS US brands...

[quote user="floobydust"] The main component that limits low-frequency response in any SET is the OPT. For these initial designs, I used the smallest Hashimoto SE OPTs... their H-203S for the 2A3 and their H-507S for the 45 which are rated at 7...

As the writer of the above-referenced propaganda, I am pleased to once again tweak the whiskers of the cat.
First off, this is promotional material so what the heck do you expect? Every brochure offers a new benchmark in performance or it is not doi...

I was pointed out to Steve Guttenberg’s video “Meet Joe, and
his amazing DIY horn speakers” at https://www.youtube.com/watch?v=EFoCVw2AJRc.
I would like to provide some commentary regarding what I
observed in there. Steve Guttenberg is an in...
