| 17208 | ADA MP1 | Guitar Preamp, input replaced with rugged jack and level control, Unit is Rev 5 low noise modified tube/solid st. RFI modified ground mods tube front end modified to be truly warmer and thicker overdrive and solidstate circuits have been more evenly matched. Slightly worn cosmetics, input replaced with rugged jack and level control.
On my website is a clear explanation about ADA MP1 and mods. Without a doubt the 3 tube mod is a waste of time and money and actually will make the ADA MP1 run incorrectly. This unit operates on the principal that the FETs control the tube voltage and carefully inject distortions into the cathode of the tube and also, the programming on the front panel changes plate voltages to tubes! A remarkably clever design! Obviously, the people who offer this 3 tube mod and double transformer mod don't understand this circuit or its operations technology and they are misleading concerned players.
The modification that I do actually lessens the tube gain, lowers the noise floor, and adds equalization that is better for today's vintage sound. Players want more versatility in programming usual guitar overdrive effects. The original design is way too screechy metal in its overdriven character for too many programs. My alteration allows a wider range of programming to go from the metal to warm, driven to crank, to a bluesy overdrive whereby the overdrive and equalization controls are calibrated more in the middle range of its programming numbers; i.e. Number 5 on the overdrive is now a nicely driven sound rather than a badly overdriven sound but the ADA MP1 will be still be able to be heavily overdriven on an 8 or 9 setting. These modifications were acceptable to the ADA engineer at the time. In fact, he commented that the electro acoustic sound with my parts change was similar to his thinking too, in that it allows for more flexibility for front panel adjustment for even more guitar tube preamping effects.
I've done this mod for 25 years!! No complaints yet. Please call me directly for more info.

| 24375 | KLH TNE-7000A | Transient noise eliminator, AKA click and pop reduction, 2 space rack mount, RCA ins/outs, PS modification plus update TL075 opamp into audio circuits, weld to ground transformer mod - call for details
Most people know the SAE5000 noise reduction system. The SAE works well on obvious pops and clicks, and is certainly acceptable for most users. But the TNE7000 is simply a superior device, adjustable for a wide range of records and cartridge types. The device operates on the concept of the click pulse being out of phase between the left and right channels as well as the wide frequency response. The best performance is realized when phono cartridges have excellent stereo separation and transient response. Ironically, many supposed audiophile cartridges are not technically accurate or actually have truly correct channel separation, especially the Ortofon moving coil designs and most conical cartridge stylus designs. The best are Audio Technica, Stanton, and older Shures, with elliptical stylus and honest 40dB channel separation. My modified TNE7000 is even better, with less obvious click removal and more range of control to remove finer nicks and ticks without overreacting to program material. I spent about six months in research designing this upgrade. | SOLD

Be aware, this is not an amplifier but a rather remarkable, super audio quality 4 channel processor. It has 2 channels in and 4 channels out which allow the unit to create delays and acoustic ambiance enhancements from the original 2 channels. This machine’s best attribute is to extract the natural ambiance (reverberation) from the stereo image and place it in the back channel as well as adding user-adjustable delay time to further enhance the natural surround/large room effect. It’s a device for the purist audiophiles who are not looking to substantially alter their sound but rather enhance their stereo to 4 properly placed speakers. Feel free to call for more info if you are interested. | $ 160
