J-Corder Performance Playback Modification

With this enhancement, you be able to maximize the signal you are able to lay on the tape, virtually eliminating hiss and providing a superior analog sound that will blow your mind. You wont believe how great of a tape you will be able to make yourself with this mod.

Four Head Direct Wired Out Playback Option with Flux
We know many of you enjoy the sound of tube playback amplifiers. This head assembly has an erase, record and play head. The first mounting position is a second playback head that is wired directly to a pair of output jacks on the back of the machine. The Flux brand head is used only for the direct out feature. This option allows the user to try any tube or other external playback amplifier, such as the amazing products offered by Doshi Audio. This is great option for those who like to use both tube and transistor amplification.

Wiring Harness Modification
This mod gives you a pair of mounted RCA jacks on the back of the unit as pre-wired for a direct output option later should you choose to move forward with purchasing the Flux modded headblock down the road. Adding this feature early will prevent the need to ship your tape deck back in for the full Flux Mod as mentioned above.

Auto-Reverse
For the RS-1700 model, the factory glued together two very small heads to give you the erase and record function.These small heads will not perform up to the ability of a full size head. The only advantage of the original design was it allowed you to record in both directions. A typical problem with any auto reverse machine is the sound quality and playback levels differ going forward versus reversed. To solve that problem Jeff, removes the two erase/record heads and replaces those with one full-sized erase and one full-sized record head. This dramatically improves the sound quality, still allowing you the convenience of long playback times while utilizing the auto-reverse functionality. 

With this upgrade, recording is only done going in the forward direction. The Auto-Reverse Playback operates as it came from the factory. The advantage to recording in the forward direction is a perfectly matched sound level when you play back in either direction. Customers who have purchased this option really love the performance.
