[Amps] Econco closing

[David Gow]

Does Burle still exist?  I can't find it on the web and supposedly NOS
Burle 8122s are for sale from India.  Maxgain says they are out of stock.
I have a NCL-2000 on the shelf, the tubes are weak so I wonder if it is now
a door stop.  My Henry 3KD is working well with Chinese 3-500s  but the
National ishure s pretty.
