126mhz Posted March 5, 2005 Share Posted March 5, 2005 Just short note to let everyone know about a guy named Roy Mottram who operates a site tubes4hifi.com and sells new boards partially finished and fully finished with tubes primarially from ebay. He lives in the Seattle area and he let me drive up from Portland, Oregon where I live to drop off my ST70 for him to work on. My girlfriend and I went shopping for about three hours and he installed the borad with tubes and set the bias on a new "Stuffed Board" for my beautiful old Dynaco. I just got home and the old Dynaco soulds like a million bucks. (Well maybe like about four thousand bucks!) He sells a great product and charges a more than fair price, and he's a heck of a nice guy too. He even fixed a few little things I didn't ask him to. Needless to say I've very happy with the work he did. Order from this guy with confidence. Bill Woodward Quote Link to comment Share on other sites More sharing options...
126mhz Posted March 6, 2005 Author Share Posted March 6, 2005 P.S. I hope it's not aganist the rules of the site to post a shameless plug for a vendor who I have had good dealings with. Quote Link to comment Share on other sites More sharing options...
Marvel Posted March 7, 2005 Share Posted March 7, 2005 I found his site after I had already ordered my boards from Curcio Audio. Someone else who is coming up with an ST70 board is Shannon at diytube.com. Marvel Quote Link to comment Share on other sites More sharing options...
sunnysal Posted March 7, 2005 Share Posted March 7, 2005 nothing wrong at all with praising someone who has done good work for you or sold you something. we only frown on self promotion...and most of the time, not even that! congrats on the dynaco! tony Quote Link to comment Share on other sites More sharing options...
kegman Posted March 12, 2005 Share Posted March 12, 2005 I've gotten the tubes4hifi boards too from roy and they are fantastic! Nice now it uses (3) 12at7 input tubes. I installed them myself and worked great. Roy is a pretty good guy! About 6 months after I installed the boards I found that craig from nosvalves didn't live that far from me so he invited me over and we went through my st70 some more with extra capacitance in the pw supply and hey changed two caps on the tubes4hifi board to smooth out a very small ripple when looked at on the scope. He has the same board mods on an st-70 he has and found the issue about the board caps. The board mods are a truly remarkable transformation of the st-70. When craig tested mine we were flat frm 10hz-35k and 42watts a channel clean! Both Roy and craig are great guys who know there stuff!

126mhz Posted March 12, 2005 Author Share Posted March 12, 2005 The best part about this web site is that it bucks the school of thought that says one has got to dump megabucks into a HiFi system to get high quality sound. The same is true for the Dynaco ST70, most all tube gear made by Scott, and several other manufactures. For slightly less than five hundred dollars over a three year period, including the purchase price, I believe I'd have to spend three to four thousand dollars to equal the sound of my lightly modified ST70. (and it's been a real education and a lot of fun to boot!) I have a old McIntosh C11 tube pre amplifier that I feel the same way about. (not to mention my completely redone Scott 299D) It's all out there, one just has to read and learn a little bit.
