If you can pull it off, build your own, using 6J5, or vintage #27 globe triodes. Use Mundorf coupling capacitors and metalized polypropylene capacitors in the pi network power supply with a Hammond choke on the grounded negative side. An amp costing 120,000 new uses electrolytic power supply capacitors which have to be replaces every ten years or less and have much worse ESR than polypropylene capacitors. One power supply for both channels has so little ESR that you will get a channel separation of over 120 db.
Tube Pre-amp Suggestions.
I have a Coda No 8 power-amp and was looking for some suggestions on what would a good tube pre-amp that would pair up with it?
