The custom builder of my linestage and power amp builds gear based on old Western Electric gear. He utilizes a lot of vintage parts in his builds. While he has done 300b triode amps, most of his builds are low-powered pentode amps. His name is Aldo D'Urso and he lives in Italy.
My pushpull amp is a rebuilt version of a Western Electric 133A amp. It utilizes original Western Electric input transformers and output transformers and vintage paper in oil caps and vintage resistors. The power transformer and choke are modern parts. The input/driver tubes are Western Electric 348A tubes (four of them) and the output tubes are 349A (four of them in a stereo amp). The use of input transformers mean that the amp is best used with a linestage with complementary output transformers. This pushpull amp puts a whopping 5.5 wpc.
My linestage utilizes such output transformers as well as input transformers (all Western Electric iron). The linestage runs Western Electric 310 A and 348A tubes. It is NOT a Western Electric replica in that it has remote control of volume.
