  • After 5 years from the time I acquired the PCBs and parts, I finally took advantage of the free time created by the pandemic and completed my KGSSHV.  This is the offboard version with +/-500V supply.

  • Not sure if we have a KGSS thread but I'll just post this here.  So last year it dawned on me that I built my first KGSS amp 15 years ago and something had to be done to celebrate that.  It started of

Great, glad to hear! Enjoy this amazing amp.

Hello everyone!

Today found your forum!

Many thanks to everyone for all that you do. 

Recently bought headphones SR-009. Who is looking for an amplifier. Please tell me, if you take the sound as a reference for 10 points. As far as points sounds KGSSHV? and such original amplifier from Stax 007 and 727? Thank you to all who will be able to orient.

I think you are asking for a reference of the SQ level to a Stax 727 or 007t? I have the 009s and still have my Stax 717 which sounds better (slightly) than the 727. If my KGSShv was 10, I would say the 717 is around 7 at most. The difference isn't subtle. Across the board better. 

Thank you for your response.
Just now you can buy the following amplifiers:
- 007- 900 $ USD
- 727 - 900 $
- Woo audio ges - 1000 $
Listen live amplifiers fails.
Therefore, I ask your advice, what to buy?
Electrostatics and love myself listening acoustics Quad ESL-2905, and can not do experiments and just buy KGSSHV or HBSE? Help Board?

This stuff belongs on HF. 

 

Now for something that belongs here...  something new...  :)

The ever so elusive Carbon... 

Neat. So when's the (carbon) circlotron going to surface? ;)

I'm holding out for the 6s4a/el34 circlotron, too many of those tubes lying around

Wow.  Very nice! 

 

Can't wait for your impressions once you get it running.

Parts and layout looks a lot like a KGST (KGSSHV front end) with SiC replacing the tubes.

Very interested in your impressions too, Spritzer. Especially when used with SR-009s.

That's pretty much what it is.  A KGSSHV with the last stage removed and the gain stage beefed up. 

Way to go Birgir!

I’m looking forward to impressions once you get some head time.

Things are getting smaller and smaller. Me like.

When you said the gain stage beefed up, how much are we talking about?

We might run it at 20mA or even higher.  Plenty of heatsinking needed....

What voltages are you experimenting with?

I'll start at 400V and work from there. 

Really looking forward to hearing your impressions spritzer, especially in comparison with the KGST and KGSSHV. 

I have to order some more parts in before I can finish this but I have the chassis ready. 

 

In other news, new KGSSHV boards showed up today.

They've been listed on my website if anybody needs a set.  :)

Is there something about the stereo board version that's keeping you from stocking it?
