Mcintosh Mc-3500 & mi-350 use the 6lq6 6mj6 sweep tube. Kirkus is correct about the transformer winding ratio's as the Mc-3500's have three separate transformers one of them being a very complicated winding configuration with only one company capable of winding this transformer.
Also 6lq6 tubes are costing around 40.00 a pop and you will need 16 for a pair of these 350 watt amps.
On the positive side these amps are one of the best sounding amps ever and will take on any S/S amp with comparable output
