*We rarely have these in stock ready to ship.

Our next restored unit will not be ready until September.

This super clean machine appears to have been serviced by the experts not far from us at Soundsmith and is working brilliantly.

Here's your chance to own a fully working CR-7A.

The front display is super bright, both meters are responsive, and the drive mechanism engages quietly and quickly.

A brief record test with reference headphones revealed great record quality and playback.

The SkyFi Testing Process for Tape Decks and Reel to Reel Machines:

First steps are performed to determine if the unit is a candidate for our full restoration process or if its just in need of a light service.

We first do a basic functionality test to ensure proper playback fast forward and rewind.  We look for smooth operation of the motors, transport engagement and associated rolling parts.  

We then do an internal physical inspection to ensure the belts and rubber consumable parts are up to spec.  

Internal components are checked to make sure that there are no signs of heat stress or damage particularly in the power supply section.  Capacitors are checked for telltale signs of predictive failure including bulging, shrunken wrappers, or physical leakage. We also inspect the PCBs for discoloration from resistors or transistors that may have been running hot. On vintage units we often spot check select capacitors for value and ESR. 

A light service will involve replacement of belts and rollers, external cleaning of heads, mechanism and boards and basic record and playback tests.  

A full restoration will often include disassembly of the drive system and replacement of all consumable and wearable parts including pinch rollers, belts, brakes, bearings.  We then clean lubricate and re-assembly the drive and perform basic mechanical alignment to ensure proper tape path and head alignment. 

Final calibration will involve adjustment of playback erase and record heads and optimization of the bias for a specific tape type.  We do this with the aid of a  Soundtech 1510A tape deck analyzer and a Nakamichi T100 unit and reference calibration tapes.  

Final listening tests are done while monitoring with our reference Grado HP-1 headphones and a variety of factory and custom reference recordings. We find that there is no better system for critical listening on tapes than the headphones specifically when comparing a live feed to a recorded feed.
