The all silver differential line preamplifier which I announced in October, has been finished since a while. I finally found the time to take some photos and test it.
The unit got finished in a dark wood (smoked eucalyptus) with graphite grey metallic transformer covers.
As with all 10Y line stages the power supply is completely separate:
It houses separate choke filtered filament supplies for both channels and a choke filtered B+ supply using the well proven full wave bridge arrangement with 4 6AX4 TV Damper tubes.
The signal section is completely free of any capacitors.
There are 4 filament chokes under the transformer covers. Inside the chassis there are 14 (!) silver transformers and chokes.
Silver volume control AVCs, silver line output transformers, separate silver wound plate chokes for each tube and a separate pair of silver input transformers for each of the 3 inputs.
But if budget is not an issue, I can only recommend to consider such a preamplifier. I am trying to imagine how it would sound in combination with a fully differential and all silver phono preamplifier, which I still have to build.
I will be able to enjoy this preamp for a little while before it will be shipped to it's new owner.
