Here's my Range Finder build. I love the 8-way switch to tune the filter. The stock RM cap (position 2 on this switch) is quite thin, and I haven't enjoyed it into dirt pedals, but I've like 3-4 more. 5-6 sound cool clean, not full range transparent but a warm mid-focused sound.
Initially I biased to Collector = -7V according to info all over online, but once I got to position 5 and beyond, it distorted easily with my middle-of-the-road tele pickups, and the distortion was not very pleasant. I re-biased to around C=-4.5V, and I find it to be much nicer. It doesn't distort as much, and when it does it's much more pleasant to me. (I assume due to more symmetric clipping, vs the asymmetric and gating at the -7V setting). At the stock RM (position 2), it doesn't make much difference that I can hear.
I'm curious, has anyone else found biasing to around -4.5V more pleasant than the recommended -7V?
To fit it sideways in the 1590B, I did have to file the top and bottom of the pcb a bit, but I was watching for any traces (besides the GND fill) and made sure to leave clearance. I soldered the socketed resistor after the picture.
The enclosure is the new metallic candy red from Tayda. I have the copper, which is not sparkly, but this red is very noticeably sparkly. It's maybe not the most vintage look for this circuit, but I like it for something different than my other builds.
