Hi Chad,

I could also bring some test equipment, if it is needed... scope, diff amps, distortion analyzer, precision meters, tube tester, bench supplies, etc. Whatever I can fit in my car.
What do you have in the way of test equipment? I am interested in the THD analyzer. If I don't need to attempt to bring my HP 339A, so much the better! I'm coming by air from the Toronto area.

ya didn't see schematic ?
Zen,
There's one problem with your "On Topic" Pumpkin thread. It's impossible to find anything "off topic" such as your schematic... I 'm afraid ony the hardiest DIYers will ever discover the pleasures of it. I guess that's the idea- they have to earn it!

I now actually TRIED (sometimes that helps) and discovered a very balanced schematic as the FIRST POST. That wasn't so hard....
Another idea is when the boards are done is to start another thread "Building the Pumpkin"
and have that one be very clear...

Hi Chris,

I have a Tek AA-501 - not quite as clean or useful as a modern soundcard + spectrum analyzer software. However, it has some nice features, and the SG-505 that goes with it is a very low distortion generator, excellent as a standalone sine source. So by all means, spare yourself the effort - YYZ-SFO is a long way to haul something as big and heavy as a 339A! Besides, the luggage space is best devoted to your projects!

I think between the locals, we probably have most of the test gear needs covered, especially anything large and heavy.

OK, I haven't yet said what I'd bring along.
It might not be too interesting , but I'd bring along a Hybrid power amp with tube front end.

It has turned out well and I'd like to see where it stands. There might be a couple of tube preamps too ! Not sure about that yet.

Will there be a turntable with MM cartridge and some good vinyl discs ?

See ........ nothing very exotic except that it would have travelled about 12,000 miles and been cryogenically (!) treated in the aircraft hold!
Cheers,
Ashok.

Don't sell it short! I hear they're pretty good.

I would love to have an HP 3585 spectrum analyzer, or one of the new ones. Real time and I trust them much more. Bandwidth way up there is important these days.

Anyway, I'm not crazy about shipping my gear that far.

Well, bring a bunch and sell them as a short run of amps from the "custom shop". They would sell!
