Are you serious that Vitamin Q caps are toxic ( at the outside ) or are you joking ?! As I have small stock of Vitamin Q caps left I am curious. I don't like toxic stuff except for tin/lead solder that is...
I am glad I built a DC coupled B1 "Mezmerize". Cheaper and less mental noise which flavor cap to pick etc.

Hi, I could not find any info on what is inside those caps except that they're paper in mineral oil. Please tell me what's in them.
Sometime the "oil" used in very old PIO caps as well as to cool down Xfrmrs was declared as toxic. I don't know if the oil inside the Vit Q is toxic or not, but I know they are sealed.
OK, I know some transformer oils contained toxic dioxines/polychloorbifenyls but I haven't found any reference to the Vitamin Q caps.
I assume this story is not based on facts.

Paper and foil actually, new production Vit-Q are impregnated paper only.
You get high on PCBs when a Sprague PIO blows, current production is selfcontaining.
OK, we are going OT here but then Vitamin Q are not toxic except of course for the lead containing solder on the lead wire connections.
On the other hand Sprague PIO contains toxic oil. Thank you for the information Jacco. It is already hard to know your components and their specific features thoroughly but these myths and flaky assumptions don't make it any easier.

A lot of general knowledge from the paper days got lost after the web-age transition.

I was referring to original Vit Qs from '50-'60 anyway, I was not aware of their "reissue".
New production is 100% safe for sure, old ones.... who knows. But unless they blow, they don't spill oil even after 50 or 60 years.

Pass B1 caps help !!
Do any of you guys have feedback on a great sounding
capacitor combination to use on B1. I am using vishay 1uf
and Axon 10uf like Nelson.It sounds a little closed in to me
I would still like the warmth but have good resolution
and a fat bass.

The B1 has an output impedance of just over 1000r
It may be the receiver that is causing your problem rather than the B1.

Hi,
I'm planning on using a diy LDR (lightspeed) volume control with my B1.
I need some help in wiring to a Pass B1 board in place of the stereo pot.
Thanks,
Kffern

Doesn't the Charlize come with an input coupling cap already? Maybe it's the effect of the two coupling caps in the line which causes that?
I thought most units have input coupling caps,
I mean even my Cd player has coupling caps.

From DIY Paradise site: Charlize has Input caps, Charlize 2 does not have.

I am thinking of lowering the 1k output resistor to 330r
I figure this may help open it up a bit,any thoughts.
