<DIV></DIV>Hi All</DIV>
<DIV> </DIV>
<DIV>One additional item is that you can use the 6AH6 instead of the 6AU6 in the
receiver RF stage but you also need to change another 6AU6 to a 6AH6 or use a
balancing resistor on the opposite heater rail to equalise the heater
currents - the 6AH6 requires 0.45A whereas the 6AU6 requires 0.30A. </DIV>
<DIV> </DIV>
<DIV>Personally I find the SB-101 receiver sensitivity perfectly adequate on all
bands except possibly 10m and with an evening noise level of S7-S8 on 80m
and 160m (special conversion) the extra gain from the 6AH6 is just not
required.</DIV>
