[HAM] An idea on AO-28 rebuilding (was C-3 rumbling)

[Bohachewsky, Andrew V.]

Hey Jim,

Are you talking about having printed wiring boards made up such that the
components would get soldered to the board and all connection made via
pwb traces? That does sound like a great idea especially since PWB
design/route/manufacture has become relatively inexpensive with all the
automated design tools and fab places that just take your design tool
files (gerber files?) and with an automated process pump out whatever
number of boards you want.

Since you already have a leg on this concept let me throw you another
idea that I've been thinking of: you might actually have more demand for
147 amp boards and that might be a simpler circuit as well. I know that
although not cheap the input and output transformers are available,
besides the tubes the rest of the components are reasonably inexpensive.
Vintage 147 amps seem to be going for $400 or more (with or without
tubes).

If a 147 PWB board could be had for a reasonable price I think there are
definitely folks out there who would be happy to shell out $400-$500
(cost of PWB plus components) to build their own brand new "147 kit
amp".

The concept could be extended to other vintage amps. It would be REAL
cool if the component layout on the PCB looked the same as the
schematics (could even screenprint the schematic On the PWB!

I had new custom turret boards priced and set to go(for the AO-28), with

or without the components on them.  This was a few years ago, and the 
demand did not seem to be there to outweigh the start-up cost. I will 
get new pricing together, and let you all know what range we are talking

about, and see if there is now enough interest to proceed.
