Great Service for AVA

I had a problem with my Ultimate 70.  Frank helped me out with a couple of new parts and now it works wonderful again.
I have enjoyed AVA products for the last 30 years.  Thank you Frank for your time, talent, expertise and great customer service!

What exactly was the problem and what were the parts that fixed it?

Hi Ron,

A 390pf capacitor on the circuit board failed, it took a 47 ohm resistor with it.  I had just turned on the amp, it was warming up, I had not used it for a month or so.  A real "Fourth of July" event.  Fireworks with snap, crackle, sizzle, lots of smoke and a bad smell too. 

Have a great evening,
Dave

It was a 500V rated mica cap, not supposed to ever fail in that application.   :(

Well yes Frank, that 390 pf 500 volt cap shouldn't have failed, kind of like the stock market shouldn't have dropped like it did (or will). 

Stuff happens.  I just want to commend you on your customer service and tell everyone that owns a Dynaco ST70 should make it an Ultimate 70.
Thanks again
Dave

Dave,

I second the suggestion that ST70s be turned into Ultimate 70s!  Like you, I'm using it with a Super PAS 3, and love the combination.  Rich, involving and I want to listen for hours.

I'm running my U70 with my Insight EC preamp and it is glorious heaven! Vinyl is to die for. My Focal JMLab 908s are an easy drive and the 33 watts per channel are more then enough power to make those baby's smoke!
