Hello im a new Dynaco Tube Audio Forum person. Thank You Bob Latino, your site and many many compelling replies to endless questions convinced me to buy within the last 6 month a Dynakit ST70 and then a pair of MKIII's.
I am new with no idea what to do on Tube amplifiers. I know how to use my meter and I know the differences in caps and resistors and how to read them. So I think I can make my way through keeping my new Dynaco/Dynakit amps running.
The stock ST70 was loved and looked after and arrived fully functional. Only necessary changes were made before I got it. I was looking for stock and un-moded units. It is being used as we speak on some vintage Cornwalls.
The MK III's are pretty much stock also but the SDS Labs capacitor board mod was installed into one of the amps. I will install the other shortly. (units are shelved until all necessary updates are done i.e.. not running) These also has some pretty grimed up Driver boards..
I have ordered the Diodes for the Selenium Rectifier replacment.
Any suggestions on what else I should do immediately on the MK III's. I only want to change what I need to to stop it from blowing up in the short term. Caps .. resistors?
Probably a dumb question but if I have the SDS cap boards installed in the MK III's Im guessing I do NOT need to upgrade the 30/20/20/20 uF Capacitor Can.?
Last question for today... Can I drop in KT88's into the stock Dynakit ST70 and simply re-bias or do i need to do a few other things under the hood to make this happen.
I will add pics ASAP as soon as my probation week is up.
I looked for the RULES area and could not find it.. I hope I have kept to the guidelines of this Forum.
Thanks everyone
Chris
