I'm reluctant to start another new thread, seeing as how I've created seven others in the past month all somehow related to the build of my G*S*G. But, since each on of those threads seems to be geared toward one specific aspect of the G*S*G, I couldn't figure out where to put the general stuff.
I started soldering last night. I stuck J1 on a little crooked, and it's going to annoy me. I'll probably have to try to suck the solder out and straighten it up a little. I also mistakenly installed R17a and R17b. I intended to use a second choke in their place, but you know how it is when you've got a big sack of Mouser parts in front of you. You just keep stuffing until all the parts are gone. Maybe I'll just save the second choke for another day. I deliberately neglected to install R13 and R14. I bought extra 51 and 47 ohm parts, and I couldn't decide whether to make the virtual hum pot 51/47 (as indicated in the manual) or 51/51. I thought I saw a post around here somewhere that suggested using matching resistors if you had sufficient filtering on the B+ supply. Anyway, since I might not be using the extra choke in the PSU, I'll probably just go with what the manual says.
Finally, I haven't quite figured out how to install the huge K40Y coupling caps. Right now my best plan is to stick them in Japanese style, with the cap sticking straight up off the board. I'll need to solder an extension onto one of the leads so it'll be able to bend over and reach the board. They'll be the tallest thing on the board, but I think that will be OK as long as my chassis is tall enough. I'm unsure about mechanical stability - maybe a little hot melt glue underneath would be a good idea?
I splurged and finally bought something better to replace my junky Radio Shack $5 soldering iron. It's really nice to have something that will melt solder, but doesn't scorch the board. I wish I had bought one of these a long time ago.
