Thanks for yor replies. I did find some specs for the Fostex Lab series 600 amp and maybe someone can help me with them.If I recall It was quite expensive back in 1984 when I bought it,I think it was around $1400.00 canadian($1100.00 us approx exchange rate back then).Since I don't listen to music quite as loud anymore,I was thinking of upgrading to a more accurate amp of lower wattage.I'm posting the specs so someone can help me decide to upgrade or keep what I already have.(These specs don't mean much to me) -RMS (min.) Continuous Power Output:per channel 20hz-20khz(both channels driven) 8ohms 200w(THD 0.02%) 4ohms 300w(THD 0.05%) -T.H.D. 20hz-20khz at 250mw to rated power @8ohms 0.05% max -Power bandwidth (IHF T.H.D. 0.1%) 5hz-50khz -Intermodulation Distortion: 250mw to rated power @8ohms with any 2 mixed frequecies between 10hz and 30khz at 4/1 voltage ratio: 0.05% max -Frequency responce at rated power: +0. -0.5 db. 10hz to 50khz -Signal to noise ratio: greater than 95db (IHF-A 115db) below rated power (at 8 ohms) -Transient responce of any square wave: 1.5 microseconds rise and fall time. -Dampening Factor: 150 min (8 ohms 20hz-20khz) 75 min (4 ohms 20hz-20khz) -Input sensitivity: 0.8v rms to rated power at 8 ohms -Input impedance: 10 kohms -Power consumption 1800 watts (YIKES) -Weight: 16.5 kg Sorry for the long post but I really don't know which specs are the important ones T.I.A. ------------------ Cornwalls til I die

I have a Sansui AU6900 integrated amp bought around 1977 I belive.Does anyone know the spec's and quality of this amp?I bought it from a friend around 1979 and he had no book for it.I think it's about 65 wpc but not sure.I also have a Fostex Labratory series 600 power amp that I've been running my Cornwalls with.I had been using the Sansui's preamp and the Fostex as the power amp for probably the last 15 years.Recently I tried using the Sansui to power the corns and was very suprised by the performance it has. Anyone know where this amp sits as far as specs go compared to other quality amps? Being 26+ years old and still sounding good it must be of good quality. Have I been running the wrong amp all these years? Any input on either of these 2 amps would be greatly appreciated.. Cornwalls forever. ------------------ Cornwalls til I die

I own a pair of Cornwall's,Ser#'s 8438531 and 32 from 1984 vintage.I was wondering if anyone knows what drivers were used in them.I removed the back to find out only to find the numbers written ink and smudged.I think the tweeter reads K77M and woofer K33E(square magnet)but the mid horn is unreadable.I was expecting to see a nice Klipsh sticker on each of them like some of the pictures I've seen in this group.This looks kinda cheap-But they still sound great. Any thoughts on what driver these are? TIA ------------------ Cornwalls til I die
