I'm doing a repair on my Forte 4a, would appreciate any schematic that anyone out there can provide.

HELP!! I have a Boston Acoustics T1000 crossover but I do not know how to wire it to the drivers or to the input from the driving amplifier. (I also have all the drivers) This late 1980's 3-way speaker system has two 8 inch woofers, a 6.5 inch mid and 1 inch dome tweeter. Obviously they all...

NEW BUILD Compact 2-chassis ß22 / σ22 2-board amp with built in DAC (note: Genuine AMB / Glass Audio parts - not cheap copies) This is a 2-board design (not a 3-board "active ground" layout.) 2-board configurations have the lowest distortion and noise of any Beta-22 configurations. The...

I bought a Nakamichi MR-1 which is clean and works fine except the pressure pad lifter- the little cage that snaps onto the playback head- is missing. Does anyone know where I might find one? Suggestions.... anyone? MISSING THE PRESSURE PAD LIFTER!!!

I just got an Emotiva UMC-200 My main setup is mostly a 2 channel music system, but I also use it to listen to TV audio. Now, I want surround sound so I added a UMC-200 to process blu-ray, DVD and cable TV audio, feed LEFT FRONT and RIGHT FRONT to my 2-channel stereo rig, and feed LEFT...

There have been some pretty good tubes coming from China lately (along with some that are not so good,) wondering if these KT90's are any good, especially for use in H-K Citation II. Matched quad going for $299.99 on the big auction site.
