I like the smell of tube-type equipment.

Reminds me of my first ham radio station.

The tubed MacIntoch hi-fi amp are now collectors items, two of those things amps weigh in a 150lbs.

There was a huge move toward solid state in the early 90's, especially for the heavy metal/hard rock crowd. The solid state gave a more 'aggressive' distortion but lost the warmth of the tubes.

Solid state for show, tubes for a pro!!!

I just think everything was built better those days, I actually run an ancient solid state lafayette Lr-1500TA reciever that simply sounds better then the newer units my siblings have.

Its a great reciever, I only lament that its nearing the end of its lifespan (right channel occassionally cuts out) and I have not the skills to fix it.

Tubes never left. Guitar players never abandoned them. And they've been popular in the
high fidelity world since Audio Research brought them back in the early 70s.
I own only tube guitar amps (custom made) and I have a Harmon-Kardon Citation II tube power
amp being restored. But my stereo rig uses Krell solid state pure class a monoblock amps.
I like both tube and solid state. I'd miss either if it wasn't available.

I think the glow is just an artifiact of the pic or lighting, hard to tell. I have had two HK CII's through here, and I dont see the attraction. They could both have been ill, but one was recently restored. Neither one was as good as my VTL. Just as well, I needed that $900 for other things. Who's doing the restoration on your CII's?

A fellow Krell man, I admire that! Wonderful, overbuilt amps.

Seriously, a good clean circuit is a good clean circuit. Tubes by themselves do not make better sound, anymore than solid state makes bad sound. It's the design & execution of the circuits and amp.

There have been a whole slew of completely SS circuits with a couple tubes sitting along side basically doing nothing, that people bought and SWORE "warmed up" and "purified" their sound.

Don't buy hype, or tubes, or hearsay. Buy quality no matter what the price or nameplate says.

In guitar amps it is impossible to get natural overdrive without a tube amp. If you can exactly Duplicate Stevie Ray Vaughan's guitar tone with a solid state amp, you could sell it and become rich.

SS is getting better. The funny thing is the SS circuit gets very complex to emulate the sound of a simple tube amp. That's why I built this:


Single ended "modern high gain type" amp with only 6 watts output so I can get the "cranked" sound at levels that are almost comfortable (when paired with an 93 db speaker).

I'm hoping to have the cabinets finished by the end of the month.

Try a 4PR400 or 4PR1000 high power tetrode! .

We used to use those in the final of a high power 225kW avg. sonar set operating at 5kHz. Plate voltage was 5.4kV and the screen operated at about 600VDC IIRC. The FM audio input was coupled across the plate to the transducer elements. Very powerful...and very dangerous. We had a total of 96 amplifier circuits in eight water cooled cabinets. The prime source of DC power for the 5.4kV plate votages were four LARGE DC generator sets.

Too bad soul can't be quantified. His tone came from his gear. "Soul" doesn't have any acoustic properties. His musicianship came from the soul (or heart, or brain, or...).

There are plenty of folks who can accurately replicate his tone. It's not rocket science, you just need the same gear (or close). Now, PLAYING like him is another matter altogether.

May need an tune-up, too. Got a good audio shop where you live? Anyone who can align a tuner can do the work on it, with any luck. Might need a service manual, though.

If your lucky, it uses garden variety tubes. Check out the AudioAsylum sponsor links on the front page for good tube vendors. Stay the hell away from ebay for tubes unless you know the vendor and track record.

Very nice. ESP makes some great guitars, their soldering inside (at the few I've seen) shows a great attention to detail. I also like EMG's, but they don't seem to use as much of the guitars harmonics (quality of wood and construction) as reulgar pickups. So I went w/ Seymour Duncans in my Les Paul classic birdseye. Can't say they are any better then EMG's though, as I really liked the sound of the KH2 I got a chance to play.

Cool setup dude. :D

had a tube gutair amp as tall as i was at the time (5 foot or so) with a tube head and 6 speaker cabinet.- not sure of the brand- thing was LOUD. Dumbass me traded it for a small SS amp...

Had no clue at the time- was probably a 70's or so vintage.

Yes flatheads are hot in period correct hot rods but a 40 year old chev. SB, much less some of the newer technology, will outperform it in every area. I've got a SC 427 C5R that probably puts out as much HP in one cylinder as a typical FH engine.

CM - I don't know why you included my post but I get the feeling our views are similar. IMHO many people don't understand that the price/value curve in high end audio is fairly straight for an inch or two then goes almost straight up. It's not that you don't get more in most cases, it's just that you pay dearly for it. Krell, Audio Research and Wilson Audio are good examples. Expensive, but very satisfying in every way.

There are few, if any, real high end shops in Atlanta nowadays. I'm sure price forced many of their former enthusiast to places like J&R and Audio Advisor. I think the tweako freaks played a part in the downfall of the hobby too. Add gun store like, golden eared, pretentious owners and the hand writing was on the wall.
