The Tr-PS-3 is a regulated bipolar power supply that puts out +/-12Vdc @ 750mA. It uses an LM317 for the positive output and an LM337 for the negative output. The Tr-PS-3 PCB is only 6" by 3.2 " and, like all GlassWare PCBs, is extra thick (0.094 in), US-made, with heavy 2-ounce copper traces. The rectifiers used are ultra-fast MUR410G types, each of which are shunted by a 0.1F ceramic capacitor to reduce RFI creation. The power supply can be used with either 115Vac-120Vac wall voltage or with with 230Vac-240Vac wall voltages.
Stereo-Mono Switch
A rotary switch for phono playback that presents three positions: mono, mute, and stereo. The signal leaves the phono stage and enters the Stereo-Mono switch's PCB. Since the rotary switch is a shorting type (a make before break type), there are no popping sounds between clicks. Kit includes the PCB, rotary switch, and several pairs resistor values to choose from, either carbon-film or metal-film types.

Hi John,

I received the Aikido PCB today - thank you for the first rate shipping speed.

Wanted to let you know that this is simply the best PCB I have had in my hands, bar none. The quality is fabulous, and your documentation is superb. I know you do this because you love audio, but I think your price of $39 is a bit of a giveaway! I'm sure you could charge double and still have happy customers.

Looking forward to building the Aikido, will send some comments when I'm done!

Thank you, regards, Gary.


Mr Broskie,

I bought an Aikido stereo linestage kit from you some days ago, and I received it just this Monday. I have a few things to say about it.. Firstly, I'm extremely impressed at the quality of what I've been sent. In fact, this is the highest quality kit I've seen anywhere, of anything. I have no idea how you managed to fit all this stuff in under what I paid for it. Second, your shipping was lightning-quick. Just more satisfaction in the bag, there. I wish everyone did business like you.
