Truth told, the HQ-140X, the 140-XA and '150 are generally the same
receiver, except that the '150 has a Q-multiplier. If memory serves me
correctly, the HQ-150 came with 2 types of cabinets; the old rack
cabinet type and later a "new" wrap-around type. The '140 has a round
S-meter, the '150 has a more typical Hammarlund plastic job. I have
both these receivers and both are very nice to use and look at.
Matching speakers a bit problematic, however. The do show up on Epay,
albeit infrequently. Good choice, either one!
