This is a very rare 8-channel analog drum synth from the 1980s. The person who brought it over told me it was designed in Germany, built in the UK and sold only in those two countries. There is very, very little info on it on the internet, and of course no service manual or schematics, but luckily all the voices are the same. The main problem was caused by the failure of the VCA in Channel 1. Continue reading “Ultimate Percussion K2-X”
The Korg Delta (or DL-50) is a string synth/polysynth hybrid from the late 1970s to early 80s, from the time when every synth company was focusing on those. I’ve got an Arp Omni 2 and Roland RS-09 of the same era here in the workshop right now and the Delta is my favorite of all three, even just based on its string sounds (to be fair, the RS doesn’t have a “synth” section).

This was for producer Gino Wong of ReRed Recording, but I was excited to get it working for my own reasons, so that I could sample the drum sounds into my Electribe. Once I did get it working, I discovered that the SCI Drumtraks is super easy and fun to make beats on! I didn’t know this before, but the sounds on here are not synthesized, but rather are low-fi samples each on their own EPROM. Continue reading “Sequential Circuits Drumtraks”
This Elka Panther 300 combo organ from the late 1960s was fully serviced by Bell Tone’s combo organ expert Darian, and is actually now for sale in our Reverb shop.
The Panther, also known as the Elka Capri, is unusually richly featured for a single-manual organ. It has a bold yet rich sound, a powerful vibrato and a wide variety of tone filters. This particular organ bears the name Capri, but it is exactly the same as the Elka Panther 300 organ, inside and out. Continue reading “Elka Panther 300”
This was a pretty straightforward repair. The Juno 106 is one of those synths which tend to always have the same issues. One of the main ones is that the VCF/VCA voice chips, sometimes called voice cards, are very prone to failure. Continue reading “Roland Juno 106”
The Moog Rogue is very, very similar to the Moog MG-1. It has pretty much the same internal design in the synth section, but the designers made some questionable choices about which parameters to allow control of– so unlike the MG-1, both oscillators on the Rogue have to have the same waveform, and be in the same octave.

This one belongs to Jeff Zeigler, a great musician who also runs the studio Uniform Recording. The ARP Omni 2 is a synth where a lot can go wrong, but it has a very, very repetitive internal architecture so it’s often the same problems over and over– bad logic ICs and bad tantalum capacitors (blue circles in photo above). That doesn’t mean it’s easy to fix though!
