My first Tube Amplifier


I have a 40 years of audio history starting with Garrard Turntable, Fisher Intergrated(SS), ADS bookself speaker on 1978.

But I started using tube amplifier on 1999.

Since then I had been using only tube amplifier in my main system.

My last SS main amplifier was Krell KSA 150 to drive Apogee Duetta Signature speakers.

My first tube amplifier was Jadis 500 which comprised of 4 pieces weighing 120 lb each.

B&W 801 driven by Jadis 500 gave most deep and powerful bass at my home.

But it generated too much heat so it was hard to use during summer.

It was memorable experience to use it for 4 years.

I may not go back to such monster tube amplifier again.



How about you?

What is your first tube amplifier?



I bet two cents on no one had used larger one as the first tube amplifier than mine.

I've always owned SS power trains. never did I even consider using glass power. never having heard speakers being driven by tubes probably fueled that notion immensely.

I got my introduction to what a fully tubed system could sound like at a local upscale audio dealership. what I heard in that room put jaw immediately on floor.

hearing how much the CDP, p[reamp, and mono blocks would cost me to take them home nearly stopped my heart! it was well over $20K! but that sound is what drove me to tubes to begin with. at least it planted the seed.
 
with that initial haunting dealership experience and knowing nothing of tubes but what was posted on these pages some decades back, my curiosity ushered me into the tube world slowly.

instead of opting for a fully tubed amp, I went with a tubed preamp first. mating that with a SS amp and things got way better way faster! that combo was all BAT. VK5 plus VK500 amp.

the BAT preamp was. informative, but expensive to roll tubes as it had 10 tubes total. it was truly an education.

I stepped up to a better preamp which, BTW had less tubes but better overall sonics, and a much higher price tag. still the BAT VK500 was the amp.


the next excursion was a mistake. I decided to upgrade both the main speakers and amp at just about the same time. poor choice IMHO. should have only done one or the other. likely just the speakers. live and learn.

I bought a BAT VK60 stereo tube amp. Apparently, I missed the lesson on amps which use a lot of tubes, but was quickly reeducated and this time about amps whose output tubes do not have suitable drop in replacements! the VK60 was OK, just not my cup of tea so off it went shortly thereafter.

while deciding on which tube amp )(s) I wanted, or could buy next, a pair of Dodd monos came up for sale. the Dodds were getting plenty of Forum press so I pulled the trigger and brought them in.

again, I'm apparently a slow learner as the cumulative tube compliment for both monos was now up to 14! lovely.

the new speakers were 93db not 87db as were the previous ones so the Dodds ran them just fine. in fact, being somewhat uneducated on IMP taps and tube amps I ran off the 4ohm taps for a while. sonic results were fat, rounded, and lush. eventually and again, from these pages, I switched to the 8ohm taps and the world took on a new sheen! that was the sweet spot for those speakers indeed with those amps.

since then life got complicated, but the desires and designs going now going forward for any outfit I generate will have tubes between the source and speakers. how many beyond the preamp will be the sticking point and decided by my preffs, and the speakers demands. hopefully, it will be another fully tubed powertrain.
