MQ-100 Project close to completion!

[gilid]

I have been working (on & mostly off) for the past 4 years on a Joe Curcio (www.curcioaudio.com) MQ-100 ampifier (2x6922 drivers, 4x6550 output). As I am writing this, both monoblocks are powered up for the final bias stability test, and I will listen to them for the first time either late tonight or tomorrow!

I will post pictures as soon as they are operational.

Salut Gilid,

I,for one couldn't have waited.
Give us the news asap,pls.
BTW,are you familiar with L'Audiophile?Jean Hiraga?
If so,don't you think these works (books) are worth translating to English (Franglais in my case) ?

Rgds,

I am now in that frustrating troublehooting phase of a project - so close to being fully completed, but so far away...

Here is a photo of the 2 amps before their first real world test. Back to the bench for more checkouts!

Fdegrove: Hiraga book 'Initiation aux amplis a tubes' sits on my bookshelf - a superb reference, especially of the single ended movement. A real inspiration. I do not know his magazine too well, though.

I will keep the group posted on my progress with my amps.

gilid,

What is the amp to the right with the PEARL tube coolers on it?

Dave,

Didn't you spot the "Sonic Frontiers" logo on it.
At least that's what it reminds me of.
BTW,these new amps just ooze WAF don't they?

Cheers,

Now that you mention it, yes that is the SF logo.

Gilid,

Your amps look superb.Sexy!
Congratulations!
RE:Jean Hiraga:The older issues of "L'Audiophile" are still the best.
There is someone in France who has put them all on CD.

Happy listening.

Good eye - the amp on the right is a Sonic Frontiers SFS-50. A few years ago, I stripped it, had it nickel plated, and upgraded the capacitors. It is a fine sounding amp, with decent WAF (Fdegrove!).

I actually did consider aesthetics when I started to work on them. I had in mind a 1950's functional look, much like you would find on purpose built lab instruments at that time. Personally, I quite like the 'form follows function' look. Actually, my wife likes them.

A cage will fit around the capacitor banks, for safety.

Gilid,

Seems to me you put in at least as much work in the looks as in the actual electrical parts.I bet it looks neat on the inside as well.

Said the Porsche collector??


Again congratulations!Inspiring looks!

Congratulations!

Looks very nice indeed
Good mechanical engineering.

Hope it sounds as good as it looks.
