Power Amplifiers

I have a "new" amp that is built mostly from very old parts and a design that was around since the 1940's.  It is essentially two Western Electric 133a amplifiers on a single chassis.  It has original Western Electric input and output transformers, original paper in oil capacitors and some very ancient plate-type resistors.  The tubes are also original Western Electric 348a and 349a tubes (very hard to find).  The only modern part is the power transformer.  This is a fantastic sounding amp, assuming one does not need much power (pushpull amp that puts out about 5.5 watts).

I have a Mondial Design Aragon 8008 BB
power amp I purchased in 1996 in Cincinnati it still in use with just a few tweaks, sounds great.

Right now I am using a late '70s GAS Son of Ampzilla. Driven by an RGR 4 preamp (early '80s). Speakers are DCM Time Windows 1A (late production). How's that for a way-back system! 

sumo polaris amp and sumo athena pre amp. i have had lots of other equipment and still do, but the sumo pairing is one of the best balanced sound sets I have ever had. 

Currently using Luxman MB-3045. A great amplifier.
