In a recent post I announced the development of a differential push pull amplifier with the 46. The first set of mono blocks with this configuration is finished.
It also uses a pair 46 tubes in differential configuration as driver.
Layout and chassis style is the same as used for the single ended 46 drive 46 amps.
4 type 46 tubes per channel providing almost 3W of '46 bliss'.
Here both mono blocks together.
They retain the character of the single ended 46 amps but with a bit more grunt and they are leaning more towards the neutral side.
Chuck Michlin who just visited described the sound as very palpable.
Above a photo together with a new set of single ended 46/46 amps with all silver transformers. More about those in an upcoming post. Stay tuned.
Best regards

Those look great. I bet if this keeps up you will consider resurrecting the Elrog 46 to keep all these customers supply stable for life. That is a lot of tubes for a tube that is no longer made.

Any more comments on the results sound-wise? And did you follow the basic approach of the early 46 drives 46 amp schematic with an interstage?
ReplyDeleteI rarely write about the sound of my amps. You can fiund sound descriptions by other on the net. Here some of teh single ended version of this amp: https://zero-distortion.org/pnoe-horns-with-aer-bd4-5-drivers-vygerthomas-mayer/
DeleteThis ampm is differential throughout and pure Class A which is different from the suggested schematic in the datasheet of the 46
