Default Kaneda 50W Class A amplifier

Hi,
Has anyone build this power amplifier before? Was wondering what 2SC1316 was used; GR or BL?

Thanks

I built a few of similar topology.
There are literally hundreds of versions from preamps to IV converters to power amps.

Just use google translate and search at :

The later, updated circuits are all in his books, and they are not expensive.

Yes, I did long time ago. L'Audiophile published a later version of this amp with a modified first stage differential and a modified overall feedback. Send your PM and I'll try to find the article and will mail a copy and my circuit layout.

BTW, the 50W class A published by L'Audiophile was not a Kaneda design, though it showed some affinity.

Hi Josh,

You can, of course. May be that you will lose the specific sound signature of the 2SA1316, however. Akito Kaneda as well as Jean Hiraga and the LAudiophile crew thoroughly examined and selected all active and passive parts for their designs.

The resistors in the picture are Shinkoh. They were ludicrously inexpensive in Japan in the 80ies and early 90ies.

Im still trying to find the article about the later version of the 50W Class A published in La Revue de LAudiophile.
