Sorry guys for the late answers but I was doing the final voicing and measurements on the crossover I made for a large Apogee hybrid speaker with its main element replaced for a third party 1m long new ribbon. I listened to our phono through that a lot too, plus the Bench valve cascode one with my HV shunt supplying it, both through a 12B4 pre with Mosfet cascode anode load I designed for it. Amplifiers were a couple of 8XEL34 monos 140W nominal, their circuit is revised.

Just to show some images of my progress.
The cases have been recycled from previous projects!
Shunts have been soldered and work fine. On the RIAA, may begin soldering today.

Thank you nicoch46 !!!

Of course I would not think of 50 caps before tunning the rest of the system.

I already built two pedja buffers to bypass the preamp but I am not sure it is the best choice due to the lack of gain and the additional caps. (My pre does not use caps in the signal line)

The Mundorfs Supreme cost 20GBP and the obbligato 15 ... I will follow Salas indications and use the china caps.

About a decent pot, I believe you indicated something from Australia before... can you point me in the right track ?

Regards

Ricardo

OK, I had to laugh Just goes to show how relative it can be. The words "cold and windy" have a totally different meaning on our side. We've got a winter so long already... snif, snif.
