Hi Everyone,
I just did all the checks and all worked oddly when powering up only one channel worked. When I checked the one 12AT7 was not coming on. I suspected wiring but then swopped the tubes and the other channel worked fine.
Upon closer inspection the one tube says "12DT8" and the other says "12AT7" so I suspect the wrong tube was sent ?
I emailed the replacement email address but was thinking ill try some tubes from ebay would "12AT7EH" tubes work ?
Thanks!
Herbert
