Hi Hugh,

I am sure you will beat the hum issue in the end

For me it is not a must to have two separate outputs - the real issue is getting a very detailed and precise bass reproduction, something that tubes are not always very good at.

However, if the GK-2 tube output does this really well and is capable of driving long interconnects (shielded, of course) without problems, I would not need any output from the SS stage

Looking forward to more news about the GK-2!

Cheers,

Jens

Jens,

Still dragging the chain..... I am going to give it to an expert on grounding, see what he says.

Output for bass can be taken directly from the SS section, though through a cap. This should work very well, in fact.

Long interconnects should be fine; Zout is around 100R.

My apologies, lots to do, have to do it all, still don't have wheels.

Cheers,

Hugh

Not sure Taffyboy, somewhere around $1100 for fully built, warrantied board.

Not cheap - but the best around!

Cheers,

Hugh

Thanks Hugh!

Would you say it would be a benefit to take the output from the SS section to drive bass alone in multi-amped system? Or is the valve output just as precise, just different?

No worries about time for me - waiting patiently for you to 'tame the beast'

Cheers,

Jens

Jens,

I do think there would be an advantage to the bass taken from the SS section, just as before for the GK1. It will be tighter, and while Zout will be about the same, it is clearly worthwhile for a high definition bass driver which needs good input slam.

Still going....

Hugh

OK. I guess this would require a 4-channel pot then?

Cheers,

No, actually not needed Jens, since the pot on this design is right at the front of the preamp, so you will only need a dual gang!!

Cheers,

Hugh

Excellent, Hugh!! So I can duplicate what I have now with my GK-1.

(As you know, the Maggie bass panel is high definition! )

Feed that Gen Z electronics engineer pizza & 'V', so he solves the hum problem super-quick.

Regards,

Andy
