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.
