Sanken 2SC2922 amp Schematic?

[gengis]

HI,
Has anyone work on or seen an amp with around 4 pairs or more of the Sanken 2SC2922/2SA1216 output transistors?

I would like to build one with those output devices, around 200W@8 minimum.

Found one class A and one class D:

I can't comment on the amps though.

Dieter Burmester's 828 amplifier used a bunch of 1216/2922 in the output.
The amplifier was rated at 200 in 8.
It would be nice if you could get your hands on the schematic of that one, so would i.

The very nice Luxman M-117 and M-03 used 3 pairs of those Sankens. 80vdc rails 200wats 8e.

Those have hfe of about 30+ on the other hand Sanken's own A1494/C3858 (56?) are 200v devices with gain of over 50+ and are pretty good sounding.

2SA1494 and 2SC3858.

The Stage Accompany SA1600 PA amplifier i used at home a couple of years had those, 12 per rail.
2 times +300 in 8.
The 1216/2922 are twice as fast though.

I still have a picture somewhere, see if i can find it.

Mr. jacco vermeulen,
Enjoy your posts.
What does Symphonic Line by Rolf Gemein uses?



ps. I have 2 of 90 million Chevy small blocks in my garage.

Rolf Gemein favors Toshiba for a long time.
After the traditional numbers are no longer available he uses the Toshiba 2SA1943/2SC5200 for his RG series amplifiers, uses Toshiba's for the drivers too.

Rolf Gemein puts a lot of emphasis on hardware.
He is one of the few who has been wrapping toroid transformers in MU shielding, right from the start, which makes his amps pretty expensive,imo.
And separated PS supplies, apart from that no real exotic parts, the clamps for the electrolytic PS capacitors in his amplifiers are more expensive than the BH caps they hold.

It is nice to read that my writings can be of some use ocassionally, Gengis, thanks.
ps i have 1 of 90Mil as a shortblock in my hobbyroom, one day i'll have it chromed, does it show i lived in the US ?

The devices of the SA1600

Pictures of the Symphonic Line RG 10.
In a 2003 article i read that RG uses these devices only in all of his models.

PS
GengisK, i noticed you have the magic B word on your profile.
I have exotic African Bubinga wood drying in the loft of my garage, to construct a 7.5' x 3.5' diningroom table.
A sandwich construction using epoxy resin for glue, estimated weight around 350lbs.
I am not your clone, am i ?

SA has some nice amplifiers. I used some of them.

2SA1494/2SC3858s are very good transistors. I made 4 amplifier moduls with them. Good sounding, and very reliable. I prefer them over the 5200/1943 pair
