Goodness, I had not intended to have this evolve into a major issue. Paul [Caucasian Blackplate], I simply wish to point out that I was not seeking technical support from anyone at Bottlehead Inc. concerning a third party kit.
And, I understand fully, that it would not be appropriate to do so.
This morning, I got up before sunrise and had nothing to do except to stare at the little pre-amp kit. The kit vendor was certainly not out of bed at my Atlantic Daily Time. So, naively of me perhaps, I put out a request for assistance on the Bottlehead Forum concerning the issue of hooking up the transformer. In my first message, I asked for anyone to send me a personal message and I would have exchanged correspondence with that good Samaritan; then, someone posted a message and suggested that I put the question to the Forum....which is what I did. And, what has evolved after is history now.,
In retrospect, I deeply regret having asked for assistance.
