Will Vincent "Dynaco" Amps

I almost forgot.... the kt66 tubes are the "coke bottle" shape and they make this already cool looking modded st70 really "off the hook"!!!

I use the Gold Lion KT-66's.....and I agree with the posts on how great they sound. I paid 150 bucks for a quad though, a bit on the expensive side if you ask me.

The KT66's did add a more spacious sound to the amp, and there was more detail in the high end and the mids. I run a pair of Klipsh Heresey's myself.

All you need to do is replace the two 10k in the bias section with a couple of 4.7k. Then put in a couple of 25k bias pots to replace the two 10k pots.

Once I tried a set of KT66's though I was hooked. I didn't even have to get any burn time on the KT's to hear the difference, it was that apparent to me from the moment I installed them.

I go through a lot of amps, but the one amp that I will never sell is my Will Vincent Dynaco ST-70. Sometimes the ST-70 will be put on a shelf for a month or two while I try something else. (I'm currently having what I think will be a brief fling with a SET amp.) But every time I bring Will's ST-70 back into rotation I am floored by its presence, soundstage, and very good. very natural bass. Upgrade the rectifier tube, leave the El-34 tubes alone. Best amp I own

Just received my Will Vincent Dyna Super 70 amp with 6L6's with triode output of 21 watts per channel. Wow!!! Right out of the box this thing is transparent and detailed with warmth in the midrange with nice tight bass. The retrieval of low level information is astonishing with my 96db Omega MaxHemp V2's (and I didn't even get my Lightspeed preamp yet! When it sees 470K ohm input impedance of Will's amp, I'm sure things will really get cooking! Thank you Will.

I realize I sound like a broken record here on Audiogon, but excepting absolute power and low frequency performance, the Dynaco ST70, fitted with modern parts, eclipses most high-end audio amplifiers of today.

I believe Will Vincent's offerings are an excellent choice for anyone interested in purchasing an ST70.
