In Reply to: scott 222 series restoration kit? posted by mr9iron on March 25, 2007 at 20:10:17:
I got my kit from Ryan Inman. He is big into H.H. Scott gear and has a lot of suggestions as to what components to replace etc. He uses JJ caps for the electrolytics and NOS Mallory mylar signal caps I think. He also has high quality rectifier replacement etc.
Follow Ups:
Just heard back from Ryan at Hot Glass, he does have the kit for 222D and it's more substantial than the VTV kit, he said he provides instruction and he can provide support via phone or e-mail.Don't think I could ask for more on this, I think it's the way to go. So shortly looks like I'll be trying my first DIY tube project :)
He is very helpful. I just like to have all the info I can first before asking for help. Don't forget to read all the rebuild information as it is very helpful. Good idea to take pictures of the underside of the chassis where all the parts layout is before you start just in case you get confused later.The nice thing about his parts kit is that it comes with a high quality low noise rectifier not some cheap crud. The JJ caps, if he still uses them, have a good reputation too.
I think this may be the way to go, I e-mailed him about doing it for me, but since I live so far away, the shipping really was a downer. I was not sure if he would sell the parts and loan advice since he could make more off of doing the restoration himself. But you can't question his enthusiasm and knowledge on the Scott stuff.Did he provide instructions with the parts?
thanks
Just a parts and parts list mostly. He answered a few basic emails. The problem is that the information is so varied depending on skill level, amp version etc. I basically printed out everything I could get my hands on off the Scott page. Especially helpful was the rebuild review, transformer section, controls and chassis section, original instruction manual etc. So you see that is a lot of information.
One more comment that you may or may not know: there are several versions of the amps. Even within just the 222c there were several revision levels of the schematics. They may not even match perfectly what is in the actual amp. Maybe someone else out there knows better. For instance, some versions used the 7199 for the phase splitter and some used the 6U8/6GH8.
So take pictures before you remove things and make sure you can make out resistor color codes etc, if you decide to touch those.So you can see that it would get tiresome for someone like Ryan to answer the same questions time and time again. I just stopped working on mine since I have a few other projects that need to get done first.
Also, seeing what other guys have done helps to know what to expect and what seems to work. So I also printed this one out:
nosvalves.com/rebuild. Don't know if the link is good since it was from Jan, 2005.My only worry is how bad any of the volume pots may be. Hate to get done and have it be noisy from dirty old pots.
I am really skilled with soldering and I have my own test equipment now so it should not be too bad for debugging. So it is time for me to finish mine.
Just gone done with my Dynaco Mark 3 (triode electronics pcb and tubes with help from Doug's tubes too). I have no affiliation with any of these guys but they have all been equally helpful with great prices.
