Refurbish a Dynaco St70

This is my 2nd attempt at getting this thread started. 1st attempt never posted. Please forgive should a duplicate arise.

I have a Dynaco ST-70 that has been in storage for several years and has few hours on it. I would like to have it refurbished and updated for electrical components, inputs, and outputs. After having searched this forum I thought it might serve me best to initiate a new thread. Looking for contacts for having this done. Thanks in advance for your suggestions. Mike

Wow Papa, what a great deal! My ST-70 came to me free as it was going to be thrown out. Have not yet sent it to Ralph however the intent remains.

As an update, I was distracted from this however finally got around to boxing my ST-70 to be sent to Ralph. It will go out this week. I will keep all informed as this project progresses. May try to find a PAS-3 thereafter. Oregonpapa, maybe I need to go garage sale shopping.

You got it out in under a year...by a hair. :-)
Good luck with the renovation. I'm sure it'll be worth it!

OK, so I have received my ST-70 from Atmosphere, purchased new tubes as recommended by Ralph, biased the tubes, and hooked to a set of Clestion F15 speakers for a trial run. Amp works perfectly and sounds wonderful. Ralph was a treat to work with, had several conversations around his recommendations as what to do and pretty much followed his recommendation to a 'T'. Ended up keeping the amp as original as possible.  I am very pleased with my choice to refurbish. Thanks Ralph! Thanks to all for their input toward this end!  As I indicated on another thread, I am still looking for speakers that mate well with this amp.
