Selling 3 sets of Tortuga Audio V2 LDR control modules with JFET unity gain Buffers and display modules plus various additional components. Full Tortuga documentation available. I can also provide schematic and Eagle pcb files of the buffer which includes a delay-on. These were part of a working DIY volume control after a DSP crossover unit for biamping and triamping.
Sold: Set 1: Complete working DIY Tortuga V2 LDR prototype chassis with power supplies, two display modules, JFET buffer, Bybee Music Rails, and PS Audio power receptacle. $230obo. Sounds every bit as good as my new DIY Tortuga V3 DIY preamp. Needs Apple remote. Unit has no input selector switch. Inexpensive way to experience the great SQ of a buffered LDR volume attenuator.
Pending: Set 2: Tortuga V2 LDR controller, two display modules, JFET buffer plus power supply for Tortuga V2. $130obo. Needs Apple remote and buffer PS.
Set 3: Tortuga V2 LDR controller, one display module, JFET buffer and volume control encoder pot. $100obo. Can be used for biamping or Bal Vol with Set 1 above or for building a V2 LDR Volume controller by adding power supplies, etc. Can operate with encoder pot. Needs replacement LDR Module and both power supplies if not used with Set 1. Apple remote optional.
Tortuga Audio still sells new Apple remote control modules ($30+shipping) and encoder pots ($23). I can include a used Apple Remote A1294 from eBay and pair it and test it with the V2 LDR controller for an additional $20.
Buffers need PS such as the DIYINHK 4.17uV Ultralow noise regulator +-12/15V 1A plus a dual 15vac secondary transformer. Buffer uses no more than 60ma.
