    PAD ST70 and opamp buffer board by Purist Audio Design

    Hello,

    I am brand new to this forum. I found it while trying to find information on the mods to my ST-70. It has a Purist Audio Designs PAD ST70 board and an additional opamp buffer board from the same company. I have found very little information on these mods. I did contact one member here, but not sure if it sent until I have finished the one week waiting period. I will also post some pics after the waiting period. I don't know if it is considered good form to post a link to another forum. It it isn't an issue, I can provide a link to a thread I have elsewhere.

    Any information on this would be great. I am very new to tube gear. It is only my second foray into it, the other being a Stromberg Carlson ASR 433 and SR 455.

    Thanks,
    John

    Hi John,

    We had a post on this forum in July of 2011 about the Purist Audio Design driver board for the Dynaco ST-70. You should send a PM to member "stewdan". He has paperwork for this board ... See link below ..

    Thanks Bob,

    That's who I PM'd. I'm hoping he has some information or another Dynaco enthusiast on here does. I must say, after adjusting the bias on the amp. It sounds very good.
