Hey LPD,
Nice Score on the ACOUSTAT TNT 200 ! I remember that amp from my eariler days in Los Angeles. There used to be a Audio shop in Northridge,CA (I think call Northridge Audio) that used to sell Acoustat gear (amoung other things) and I spent a LOT of time in that shop. In fact, I bought a pair of DCM Time Window there. Good luck with the Amp. I am sure your JBL's will love it! Let us know.
