Self Intro

I am new to the Dynaco Tube Audio Forum, but I have a long history with Dynaco amps. I
Bought my first one in the late '60s when I was still in my teens. On the advice of a good
friend, who was finishing up his EE degree at the time, and had already designed and built
his own amp, I purchased a pair of used, kit Mark IV's and a PAS-3 preamp. Hooked them up
to a pair of AR34 speakers, and enjoyed them for years, before I sold them, some 10 years
later. In the 80's I bought a Dynaco factory built IC amp, that I used for years before it
was murdered by an unfortunate series of events. Since then, I've been using a Carver amp,
for the most part.
In the late 90's a friend at work gave me an old kit built ST70 and another PAS-3 preamp.
This is the amp I'm currently working to restore.
I am not particularly electronics literate... My background is in concrete construction, and
more recently, I eeked out a degree in Mechanical Engineering, and I now design and build
process control systems.
But I'm not afraid to tackle new things, and I enjoy the do-ing, and the music when it's done. I'm looking forward to getting the
ST70 hooked up and running.
One more note... I've been using Dynakitparts.com as a resource for parts for this project,
and I want to complement Kevin for the great service he has provided. Absolutely THE first
place I look, and would recommend for parts.
Happy Listening!

I've caught up pretty well now with most topics, still reading.

I haven't posted yet but I need to add my support for a great guy. I also buy from Kevin and I would like to second that emotion about Kevin and Dynakit...excellent service, top notch parts, and a top notch man at the helm.... :}

Kimla,

You sound just like me. I was a bit apprehensive about ripping into one of these little gems until I actually got going with it. My background is high voltage power distribution, terrestrial communications and cellular communications construction. It took me about 2 weeks of messing around off and on to build my first 70 and about 2 days to do the second. Now I can probably build one in about 5 hours. I've never bought anything from Dynakit, but apparently Bob and Roy do quite a bit of business with them and they are great guys, so Dynakit MUST be a great place to do business with. Good luck with your project. You won't be sorry...

Well my dear little ST70 (little, indeed... my daughter thinks that the "70" is it's weight) Anyway, it's done and has been running for a month or two now... Had one final hicup last week. The vintage "Radio Shack" (made in Great Britain) EL34's I found out in a drawer in the garage faded on me, so now I have 4 Russian Mullards, but they sound great, as far as I'm concerned. My son came down from Seattle and later had nice things to say on his blog: http://www.spintheblackcircle.org/search/label/audiophilia There's a photo there too!
I have no idea where those Radio Shack EL34's came from... where do I get all this junk?
