In Reply to: RE: What IS build quality? posted by pictureguy on November 28, 2014 at 19:40:23
It has multiple levels: Most important is ALWAYS the soldering. Then there is the circuits and the component selection. Then, there is layout and mechanical design. Some equipment is utilitarian and some is a work of art. I rather not pay too much for the work of art, though.

I've had mil-spec soldering training. So I understand that being Very Important in a point-2-point wired amp, like many tube amps.j Good 'wetting' and 'flow'.
The motto 'The Bigger the Blob, the Better the Job' does NOT apply to this operation
But? Once you set up a wave soldering machine? You can finish maybe 100 stuffed boards per hour with 99.9% repeatability. Maybe MORE.
Also, the choice of solder is very important. Some of the ROHS compliant stuff is, or appears to be brittle and subject to cold solder joints from heat cycling of a joint.
Too much is never enough

Aside from a few flaws in the woodworking, how would you rate my build quality on this 14 tube power supply? All the wiring is silver plated with Teflon jacket, NOS Amphenol sockets, and I used parts that are rated 50-100% over specification, and 1% or tighter where possible.
Seeking honest criticism here. Yes, I know the wood is a bit grungy, that happened from moist storage.
This is the belly of the beast, the circuit board (hand drawn and etched) is for the saftey circuit, which quickly drains the HV+ should bias fail or the umbilical to the amp come unplugged.
The AC power input. Yes, the holes in the aluminum are a bit rough. I made them 15 years ago long before Front Panel Express was an option, and I had inadequate tools at my disposal. Yes, those holes kinda suck I know that already!
Close up of one of the rectifier sockets. Ever try to make twisted pairs with Teflon wire? It can be done, but it's not for the faint of heart. Just thinking about it makes me feel like I have arthritis.
Thoughs, comments? This is the power supply for my monster amp. I intend to better this build quality substantially in the amplifier, and essentially make it as close to a mil-spec piece of gear as possible.
Thanks, Mike I appreciate the praise.
I probably could have laid it out for shorter wire runs, but it is what it is at this point.
That is a great looking piece of gear!
Good job, very well done!
