Tube output stage

My beloved B&K Pro5 with a 6922 based custom output stage got fried by a unauthorised 220V input! Aargh!! Apart from a MF X10-D buffer, has anybody got any other(preferably cheaper suggestions? thanks folks
Used Cary
Yeah, sue whoever plugged it into the dryer outlet!!!
X-10Ds go for around $125.00, just how cheap is cheap?
It wasn't that! The problem was @ the external power meter box: the list of stuff I lost...
another vote for surge protection and home owners insurance !

Sorry for your loss

I also believe that it cannot be cheaper than MF X-D10 V2 ...
