The amp was delivered today and one channel on source 1 was dead and the other sources had a bad hum that got louder as turn up the volume. I bought it off eBay and I am returning it,I was willing to send it to Raven for repairs but the seller wanted me to return it.

- Audio Mirror 6as7. Twenty watts single ended. Around 35 pounds each. 

Same chassis/transformers support the mighty 6c33 monster Russian triodes leaving these massively overbuilt. 

Simply amazing on both Jubilees and LaScala. Brings out all possible bass from the LS.

Not too much else!  It's a simple digital only system but the speakers I'm super happy with (about a month old now) thanks to you all on the forum.  Made a variant pulled from all the ideas here using JWC's "tallscala" type of thing.  Volti crossover, LMAHL Tweets and eliptrac horns with BMS drivers.
