Hi There,

Crack is working! I'll get home today for a first sound session.
Thank you Bottlehead! I'll upload some more pictures later.

I really like that headphone jack, and the RCAs, too.

Just ended up a long music session (if it was my call I was still listening), this amp surely sings!
The most notice character is the great separation I never heard before!
uploaded few more pictures.

Yess, great separation with mine to. nice job. BTW, your jack is the second I've seen w/ the gasket. Mine did not come with one...its the nickle version though. I wonder why that would matter though?
Cheers

You'll have to buy the gasket separately, it's not a part of the HP Jack. And it's only aesthetic, no other advantage or so. LA |

Hi All,
Just finished the speedball upgrade! that's sound even better! Photos updated! voltage test is ok.
Had to use a small "bridge" to connect the speedball large plate to the other tube A pin, the suggested pin was too crowded with cables under...
I hear hum noise if no source is connected and I turn the volume all the way up, is that normal? or I should be dead silent same like when a source is connected?
Also, while doing the SB upgrade I've accidentally touch the film cap, very shallow and light touch (see the pictures), do you think it's ok or I just destroyed the cap?
Thanks for everything,
LA

The proper way to test hum is with the inputs shorted rather than open. Leaving them open allows noise in and causes some hum. Of course turning the volume all the way up is an unrealistically high volume level. What matters is the normal listening level.
That said I wouldn't be surprised if you turned it all the way up with shorted inputs and didn't get any hum. That assumes a top notch build. My Seduction has always had a very low level hum. But most folks don't know it is there sitting at the listening position and at listening volumes.

Yeah, Crack is really quiet. With open inputs, I dont know. But wide open with a digital source connected, not playing, amazingly quiet. No hum with mine at all. I assume it would be the same with shorting plugs on the inputs.

Well, that's the same that thing I'm getting: shorted or with source connected I get dead silent even with volume knob all the way up.
What about the cap? what do you think? I'll try to get a better photo when I'll get home...

If the cap is playing you are fine. If you damaged it I think you would know.

I liked those connectors so much I actually copied you and ordered some from a store on eBay that carries Neutrik stuff.

Hi all,
I've been enjoying my crack for a few week already. but what's next? (I'm addicted)
While waiting for the BH DAC (hoping it'll be in a manageable price point)...
What will adding a power supply cap bypass and a choke will add?
How do I wire them?
Meanwhile, I've waited for the base to fully dry out and now i'll do the last sanding and painting.
Thanks,
LA
