£200 is about right for their utility adn portability.
Demo alongside anything under £500 and it will win on most counts.
They are small and they really punch.
They stuff an Ashdown 300 and give the 500 a good run for its money.
They have the same power supply as the AH300 - difference is number of output transistors.
As always with bass stuff, more in = more out, so beefier sounding than the AH300 (which 'needs' that power).
Main reliability iissue is the pre/amp cooupler. Fiddly to get at, but a hardwire fix sorts that stupid clip thing they used.
After that, it is contact cleaning.
I have two very scruffy ones that I wouldn't take less than £125 for.
