Barry,
i was not aware the boards are only available to MTH certified technicians. However, I think that is best. Having worked as an electronics technician since 1976, and now in engineering, I take the warnings on the manual about using a static pad and wrist strap and the warranty being voided once the static bag is opened very seriously. I had toyed with the idea of upgrading my PS1 B&O E8 ABA set myself, but will take it to Dave Minarik's Mercer Junction instead.
Thank you for the answers!
