Hi Alex,

At least CJ should know. You could maybe just try writing to the service department.

Ed is long retired. Did you e-mail to service@conradjohnson.com ?

A little late here, but I have the 'XS' conversion info. I got the four attachments from Ed a few yrs ago. However, there is a possible conflict in that the schematic suggests a circuit leading to the output tap be removed (circled 30pF cap). This is not mentioned in the written instruction steps, and I don't understand what that output tap circuit is doing.

I got the needed parts, but waited too long to dig into this project and unfortunately, with Ed gone, I don't think this type of customer support exists at CJ anymore. If anyone can reply with insight to the output circuit being severed by the 30pF cap, I think it would benefit a few of us.
