Default Audio Innovations Classic 25 web page

I've made some web pages about my Audio Innovations Classic 25 push-pull amplifier. For those who are interested, have a look at:

Hi,

Reminds me of the days I met up with Ed de Jong, PVW and all the other folk of Audio & Techniek...

Thanks for putting it up on the eb.

Cheers,

An interesting looking circuit -- i cleaned up the big schematics & giffed them so that they are clearer & smaller. If you'd like them mail me.

Hi

Funny that you mention this. I used to work there as well, it is actually how I got to know Marc somewhere half way 1995. Few months later we started the DAC design.......

I know you did, I probably must have met you somewhere along the line.

Occasionally I went to Eds' place to deliver some valves and have a chat.
In those days, from the mid eighties to the mid nineties, I sold valves to most shops in Holland.

I noticed Fust is still carrying some of the NOS stuff I sold him.

Oh, there was Menno VDV as well...he was planning on building an OTL amp with EL519's...

Siltech/Sphinx was another customer of us as well.

Small world, isn't it?

Cheers,

Hi Guido,

The company was Reference Audio.
If I'm not mistaken we had some ads in A&T but not on a regular basis.
Main activity was distribution of valves, occasionally I also did some consultancy work and design.
My last work was a range of cables I designed for Deskadel, I think Bert Doppenberg distributes them in Holland.

In those says we called everyone by their first name, Ger Fust should definetely remember me.

I don't know what happened to Ed de Jong though....
Michel de Goey and his co-engineers where really MOS-FET guys, I suspect the valves where only there to help sell the product.
They made the unfortunate choice of designing with the E288CC which was hard to come by in those days already.

Regards,

Yes, I remember reference audio. Ed is now into audionote.nl. E288CC is a nice tube, but way too much distortion. I do not understand why people like them. Have several lying around !

bye

Default I DO ....

Hi,

The main attraction of the E288CC is that it's a low noise valve and can sink a lot more current than the ECC88.

Granted, it's not as linear but I can see the attraction as the output tube in preamp and DAC service...

There is at least one better USSR valve out there...but it's getting scarce as well.

Cheers,

Hi Frank

Yes I know, 288 could do as an output stage, but to be honest I do not nee that low noise in a line stage, and still, driving it at higher currents, it is not as linear as an 88.....

I'd prefer E182CC then.

Curious for your USSR valve :-)

all the best
