I can play the aqualung lick,and some great shots EW! As the main JHS guy,are you going to be doing a schematic in the future? Thanks

I'll give it a shot but many details can't be seen in the pics..

Here's how I see it:

a bit neater:
The resistor in the bass section must be 1k of course (like in the Hornby Skewes Bass Booster). I can make out the red band clearly and the other two are dark.
I believe the two missing capacitors are most likely 0.1µFs (right - like the Bass Boost ). We can be pretty sure about the one on the collector. The Treble Booster has 0.001µF there. 0.1 and 0.001µF in series isn't that much lower than 0.001µF.
The input cap might be more debateable..

Well, it's just a Hornby Skewes Booster with switchable output section.
The bias resistors are different from the silicon version of course, but we already knew that from the germanium Treble Booster pic. The value that's new here is the the 100k from base to -9V. That one wasn't visible in the other pic.

That's the beauty EW.I've built a silicon booster with a 4061 in,and a switch for the debated input caps,but never a GE version.It's like you've given me a jigsaw piece i had missing!

good question.. it's hard wired to ground.. but the 10k/1k joint and the 0.001 probably aren't.. I'll update my schematic..

your post subjects are funny
Aldi?
Aldi?
Aldi number 1 dude!The quality of german sausage and other meats,also dutch like frikandellan,are much preferable to the mechanically seperated twine and cereal we get from sainsburys.Cheaper too.DPDT on the output network?

Funny how cheap Frikadellen are the one thing I wouldn't buy from Aldi
DPDT indeed
They used DPDT switches for on/off on the seperate Treble and Bass boosters, too, but didn't wire them up for true bypass.. same deal with the Rangemaster. Disconnecting the battery took priority...

I lived in amsterdam an zwolle for a few years,and got a thing for those glass holders,u put a few guilders in an took a frikandelllan,them went in to get some frite saus
lekkerer!

I think I spent 100 bucks in those things in 3 days.
nice work on this one. I'm gonna mark it solved.

well, nearly.. anybody know the guys at solidbodyguitar?
Sorry 'bout this.My edit function seems to go after a minute?.So EW,the cap off the collector but before the t/b network,is 0.1uf to your mind?.And the input cap the same?.Thanks again mr.jhs!
