The DAC90a is an improvement, and just looks nicer as a chassis. And it does not get so stinking hot. However, the DAC90 does perform slightly better!

The DAC 90A
is a much improved design, the tuning knob on the DAC 90 was on the side of the set, this caused problems when tuning, due to being next to the aerial. As you moved your hand away the set went slightly off tune
In the newer set the tuning knob was changed to the front, while the wavechange was fitted to the side.
Internally the newer model is much better to work on, the nasty asbestos lined dropper box was no longer required with the new rimlock valves, less power to lose via the much smaller dropper. At last the back panel was no longer likely to catch fire!
