Murphy_t. Any suggestions, the SAE X25A is the only high powered class A amplifier we have available, the valve amplifier is noticeable better in bringing out subtle low level details than any class AB Solid State amplifier we have tested so far. We want to test the valve amplifier against a Solid State amplifier which is guaranteed not to produce any form of crossover artifacts whatsoever, and only a class A amplifier can guarantee this. We believe that crossover artifacts, although virtually impossible to measure by normal tests on a good amplifier, are actually additive on real programme material, particularly on subtle low level stuff, such as choral singing and church organ. The valve amplifier seems to seperate the voices into individual ones, even good Solid State amplifiers does not do this as well. We also want to do some serious tests with different speaker cables. The valve amplifier does not appear to be affected much by various types of speaker cable, and maybe a class A amplifier will show the same characteristics in that regard.

SAE X25 Class A Amplifier Circuit
We have an SAE X25 Class A Stereo Power Amplifier. This Amplifier have been "Butchered" by an inept service technician, sections of it has been modified beyond recognition. We wish to restore this amplifier, which we believe was particularly good, and use it as a reference amplifier against a very high quality valve amplifier we are developing. Does anyone have a circuit diagram of the SAE X 25 to help us to restore the unit to original condition? Please contact poulkirk@elan.com.au or post details here.
