Pretty close to final layout...

Afternoon Tea for Joanne's Mother's 90th Birthday There were plenty of finger sandwiches With the crusts cut off, of course And there was cake, Birthday Cake!

That would be Raffy, some threads get trimmed from time to time.

Kerry is the new Cavalli except you know... well engineered products and built correctly.

I'd love the help I'll PM you. Edit: It will have a chassis ground. I've got a couple of ideas. Here's some renderings I did of the chassis. Pretty cool...

Happy Birthday my icelandic friend. I wish you have a great one Stay away from that dangerous Brennivin of yours

I had some comments back so I've made the following changes: I reversed the SE and balanced outputs I fixed a mistake in the schematic for the negative off-board voltage regulator Thanks to Kevin (of course), Birgir, Marshall and Joachim for your feedback Here's what might be the final...

I read some of what you have written elsewhere, and its becoming clear you don't have any idea what you are talking about. The apex amplifier linked to above is a single ended amplifier, that is there is a single output tube driving an gapped output transformer that carries the full dc of the power supply. The rise time and fall time of the output signal is not the same. The eddie current tube amp pictured above is a push pull amplifier with 2 output tubes per channel. The output transformer is not gapped, and there is no dc in the transformer. The rise and fall time of the output signal is the same. In fact with both input and output transformers, that amplifier can be considered as fully balanced, and fully differential. Big difference in the kind of sounds that these amplifiers make. Now, since a couple have sent me emails about the black widow, here is my explanation of whats wrong with the picture above. Now maybe in the 2 box version the board had to be that size, and was obviously stuffed into a box of a specific size. But designing that way is stupid. In the single box there is all sorts of room to make the board bigger and do a much higher quality layout with better and bigger heatsinks, and having the left and right channels be absolutely identical. The worst offender of differences in left and right channel layout was the melos, but the liquid fire, liquid lightning and especially the liquid glass are in the running. The power supply board is obviously new, full ground plane on top, suitably sized heatsinks secured to the board etc, why use an amplifier from 2007. The stax mafia can (and probably should) do a much better layout with larger heatsinks, identical channels etc. There is absolutely nothing unique about the circuit design. If its going to be eye candy on the outside, it really needs to be eye candy on the inside if its going to command a premium price.

You know that there IS a solution for that problem. But it's a slippery slope looking at the board now, its an astounding job. and its only 2 layers. infinitely better than the "professional" crap

3200 people in Hull. Hull - how on earth that number of people in *Hull* were persuaded to strip, then be spray painted shades of the sea from head to feet is a matter of astonishment. All shapes, sizes and ages. It was the news coverage, where this mass of people walked through the city centre. Absolutely no passers by took the blindest interest - almost "Well - this is Hull on a Saturday morning - what can you expect?" In this world of woe, this all leaves me refreshed and makes me smile.

A shunt regulated power supply, with some daughterboards replacing the crappy voltage references I was using in the CCS.

Not looking to go into business. Just having fun

Ok. I need to add labels, but otherwise I think I've got this where I want it to be. I changed out the power switch for a thinner one and change the power led to a through hole. Also, I went back to a 4 pin XLR jack for the output. Since I also have a 1/4" phono jack, this should not be an issue. I've also added additional patterns for the +/- regulators from ebay as well as standup heatsinks for them. I don't have a specific chassis identified, but the FPE custom enclosures will work. I'll likely mill mine myself. Any other thoughts?

What a pity, from the outside it looked like Nagra stuff

I found the block where TICE @swt61 needs to live in Portland:

2nd interview was just scheduled. I think that means I have the job.

Thanks for this guys. I had lovely day with great food and even better people. The weather was perfect too and even though it is midnight, the sun is still shining.

Belated birthday greetings Greg! Go Lance! Cheers!

Happy belated Greg! It must be very cool to follow Lance and such an amazing sport! Enjoy!
