CTC Blowtorches for everyone!

Chris main point was the "accessories", and his main issue was the sigma22. I don't see any reason that this won't work, and Kevin and Ti have stated the same thing. Nate's point is more general. The parts and topology in this amp are very standard. I'm not sure I understand the risk. It's not like your going to find another JFET to use or something else more suitable for VAS stage. And the diamond buffer is pretty straightforward, wouldn't you agree? I would agree if we were ordering resistors, but it's not as if the semiconductors won't work in this topology. If you have a particular concern about parts and their intended use in the circuit, please let us know!

if/when Jacob reads this thread I'd like to offer another suggestion of adding another set of pads right next to the current pads, but spaced out slightly axially so a second resistor can be piggybacked on top of the (currently) single ballast resistor per output device. I'd like to experiment with lowering the ballast resistor, as I'm expecting we will get good matching...plus this will allow more power handing here in case we want to up the bias substantially.

I'm glad this thread was made, 'cause there isn't one a day over at HF or anything...

Which of these does not belong? heh.

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! what for sissy "wood burning" projects?

80W-90W per channel, obviously

my guess still stands

ArchLinux with ABS is pretty cool little gig.

meh. I'd guess 80W-90W (I don't know what the CCS are set at in this version, hence the range)

ok, fair enough

This is exactly the problem in fact.

Mike: Just out of curiosity, was there a vast difference between how your turntable setup sounded in meet conditions and at home? Probably a worthless question, but just curious

ahhh... heh

huh? what about just using USB to convert to i2s then into the NOS DAC? This is exactly what I do.

Sorry, the MMG simply doesn't have a huge sound stage. If you're looking for a huge sound stage, try the Vandersteen 2ce signatures.

I would have never guessed Poplar would look like that in a burl. It's such an even kilter wood.

right, but it's quite simple to adapt. Just leave off the regulators and the bypass caps, two pieces of wire and you're done!

what was it that tipped you off, all the avatars?

ahem.. I knew there was a reason this thread belonged in the Casino. Looks like you can get free samples of the OPA445 recommended in Kevin's schematic in both PDIP and SOIC from TI now.

heh, ok I was being sensational on purpose a bit deepak started it.

I love those heat sinks. I am using four double height versions of those.

well, the spreadsheet is just the same spreadsheet that Jeff sends as an invoice.

have you purchased from Glass Jar Audio before?

I'm a firm member of team single chassis. Dual chassis is/was FOTM, meaning something the consumer wanted, but something the serious designers saw issues with... perhaps, people are suddenly realizing that.
