    After almost three and a half months, the KGST is finally in operation, and is sounding great. Thanks to all who have responded to my questions and given guidance. I am really surprised at  how good t

  • Thanks to the NYC Spring Meet yesterday, I was motivated to finish casing up my KGST.  I'm very happy with the result.  The chassis is 7" x 12.8". Perfect for my night table   Here's the beast in i

Thanks guys !!!!

To all who own a KGST and a KGSSHV. Which one do you like better with the 009? 

I have a clear preference for the KGST that persists even after rebuilding the on board KGSSHV with c4686 instead of 1n100d. I would have expected them to become almost equal, but to my ears the difference is not small. 

 

Can anyone else share their impression on this? I am even thinking about selling the KGSSHV and building a second KGST or just get a BHSE?

I like the full-size KGSSHV 450V with Sanyo parts better.  Tonality it is very simlar to the KGST but the full-size KGSSHV throws better soundstage and it is more resolving to my ears.  The KGST w/ GE tube has smaller soundstage so it is more intimate sounding to my ears. 

Very nice job, Jose!

 

What chassis and power switch did you use?

Thanks guys.

 

I use Modu Pasante chassis but I add a lateral panel in the middle.I like separate compartments ::) 

i have made a board to suit the DACT.

Hoping everything is right.

The KGST's baby brother lives, say hello to the KGDT...  :)

This is the same circuit but uses the common noval dual triodes instead of the 6S4A.  While this opens up a whole world of tube rolling it does mean it must run at lower rail voltages (+/-300V) and a bit less current.  This is the SRM-006t to the SRM-007t but also not as it doesn't suck.  ;D  The switch on the PCB allows to select either 6.3V heater tubes (normally with a shield) or the 12.6V ones with a center tap.  The amp was designed around the ECC99, 12BH7, 6CG7 and 6n6pi but there are a lot of others that will work.  Some old computer grade tubes that can be had for next to nothing that I will try out. 

Lurvly!  O0

Any problems with the lower voltage swing during typical use?

Nope and it sounds lovely with ECC99's and the SR-207 in my test rig.  Very little compression as I push the volume. 

Very neat design.  What size footprint do you figure on the box, realistically?

 

HS

That box is 330x300mm or so and I wouldn't go much smaller than that.  The problem will always be the height though as the tubes are quite tall so either cutouts for them or 90+mm height. 

That's a good size for those with space challenges.  I'm not too bothered about height but the lateral dimensions I need to manage.

 

Cheers.

 

HS

The switch idea is pretty neat. I like it.

How do you like the KGDT with the SR009 Birgir?  Thanks.

Haven't tried the 009 yet but that question is difficult due to the choice of tubes.  Only tried the ECC99 as of yet so I have some testing to do. 

i have made a board to suit the DACT.

Hoping everything is right.

does the DACT go on the other side of the board or on top?

I'm a happy camper...

headinclouds FTW....

 

 

;D

Internal shot please?  How about the back faceplate to show off the connectors?  Love the look of the amp man!  Congrats.

Thank you, purk.  I will take some pic's tomorrow of the arse end and post them up.  I do have some shots of the internals, but I'll leave those for headinclounds to post if he so chooses.  It's his baby.  I'm just a caretaker  ;D

 

chinsetta - I am listening with a pair of Koss ESP-950's using a Koss to Stax adapter cable.  The DAC is a Beresford Caiman MkII...nothing terribly fancy, but I find it's a very good converter especially at its price point.

 

HS

Really nice!

What finish did you use on the face plate?
