SPL AUDIO POWER STEREO 70
With its operation in CLASS A and with the KT 88 lamp at three-way operation apparently offers the best results.
The feed is 3 times up from that which is needed and this gives to the amplifier the possibility of an energy convenience at the speaker.
The protective glass is PYREX so as to withstand the high temperature that produce the 10 lamps that protects.
The frame of the system is of tropical Abura wood for the maximum resistance in the high temperatures.
