If my $6k amplifier can't break a 50% free-throw average, I'm putting it up for sale immediately

LOL, I guess you missed the $2400 tag. Now look at them again,  sure they sound astounding!

 

I must have acute visual deafness.

 

Anyway, if the owner can put up with them, beauty is in the eye of the beholder.

He paid for them - he'd better like them..........

 

( I can see a For Sale ad in the appropriate thread soon. Transformer feet for your BHSE. Makes the amp sing like a Cmoy).

I didn't see a biasing tool or instructions in my BHSE box.  How do I bias it if I want to try out other tubes?

post #2150 of 7103

Lift up the left side of the amp with 3" blocks?

 

You need an alignment tool/screwdriver or something like this.

You don't need to lift anything or to buy any special tool, any small flat screwdriver will do. Also changing tubes will not affect the bias. What you need is to adjust DC V offset between "+" and "--" of each channel and  between L (+/-), R(+/-) and ground.

Sounds easy enough.

post #2153 of 7103

Unfortunately that sound like greek to me. I saw the instructions on page 95 and still wasnt entirely sure... yes, E&E subject has always been a problem for me.

 

Is there detailed instructions anywhere or better yet a YouTube video? One other question is that each matched pair of EL34 should be fitted left-front and left-back or left-front and right front? Haven't been able to get a response out of Headamp so any help will be much appreciated.

The left EL34 pair goes left-front and left-back. It looks complecated but ones you do it you will get it.

you absolutely do need an insulated screwdriver. Or the plastic alignment tool.

Thanks on the tube positionining. Now to figure out how to adjust the DC Offset.

The adjustment tool should be in the box, mine came with a yellow Vishay branded one.  I would recommend using these only for the trimpots as normal screwdrivers and high voltage are never a good match.

I didn't receive this adjustment tool with my BHSE, but written on the inside flap on each tube box was where to position the tube.

geez, that's ridiculous! given the care and the time it takes to build these things, this stuff should have been taken care of long before they were ever boxed up! this is a basic safety issue. it is also a strong recommendation for going with solid state products!  how about building the kgss hv commercially?

Bah, safety is overrated. Live on the edge!
