There are a few things worth noting.
The max width on the new hypnotize is 25mm for the 4700uf caps, and up 10mm with snap ins.
The 68R's are now 2x47 (4 total), or one can go much lower in 'hot rod mode' to 10R 5 watt or so, with really adequate heat sinking.

Update,
I did order the boards during the Chinese New Year, so they will take a week or so longer to get here. They are going into production NEXT week. I apologize if I made promises to get your boards sooner.

Good morning,

Iīve been trying to follow the thread for the last couple of weeks but got lost in the meantime.
Iīd like to built the DC-coupled B1 too but I havenīt really understood what I have to order. The Hypno seems to be the latest version of the PCB - correct?
Whatīs the Mesmerize?
And apparently there is also the option of buying matched JFETs - correct?
I can supply a paypal account so paying shouldnīt be the problem.

Iīd appreciate some explanation/advice.

Cheers,
Kai

Hi Kai

Hypnotize is a DC coupled version of the B1 buffer that is optimized for hotroding ( run in higher current -ICCS- == better sound quality ) and offers no input selection ( which can be implemented by you )
Mesmerize on the other hand is a version that is not optimized for hotroding ( but can be hotroded with some modifications ) and offers input selection ( 6 inputs through relay on the board ).

Appart from that, the boards have no other difference.

Leds, relays, matched or unmatched fets are being offered by other members of this forum. You will find them in Swap Meet.

Cheers
Michael

Hi Miachael,
thx for the quick reply- much appreciated.
Since I donīt need to switch between sources I would be fine either way without having to tweak anything.

Further on to my previous question I am wondering whether there is a way of setting the B1 up for symmetrical (XLR) in- and outputs.
I think this topic has already been discussed here but unfortunately I cannot find it here.

Thanks!

Cheers,
Kai
