Darling amplification 1626 + 717A
Hello all,
don't want to look like a curator, but I've been changing amps recently just to check performance with the Magnepans basically.
Do any of you have some experience to share with this amp topology ? I'm completely ignorant with this...
I recently acquired a valve stage equipped with 2x pentodes 717A (Western Electric) and 2x triodes 1626 (RCA) and their corresponding SE transformers (from Ask Jan First), based in a circuit by Gerd Reinhöfer. 0,75wpc !!

My speakers are the Audio Note and the Magnepan SMGa, both quite different, both 90dB efficient..., so I dared connect the stage (remember: 3/4 of a watt!) to the Magnepans (I said, "ok, if something has to be damaged, I prefer it to be the Maggies"), using the Wadia 15 as a preamp (digital vol).
The huge surprise was that the rig sounds, and marvelously, I need to add...!!
Sound is BIG, hardly second harmonic distortion traces and not consistently. Clear detailed, SE three-dimensional.., a very confidential sound; real piano tones, nice vocals, sinks into blurr with big orchestral sound..., betters the Audion EL34 in many camps...
...Cosa: Magnepans (smaller) CAN sing with hardly 1 watt at 300€ !!!! Astounding.
