I did the conversion described in May 1996 QST by George T. Daughters,
KG6K, using a single 4CX800A/GU74B tube. It works OK. However, I believe
that a better cooling system will be in order.
By the way, I also did replace the electrolytic condensers in PS
section.
Cannot comment about a fair price for MLA2500. I've got mine for $250.
Good luck.

Subject: [AMPS] Rebuilding an MLA2500
I would like to try to rebuild a junker MLA2500. This is a nice
little
amp but the tubes are pretty expensive to replace. I think
there was a
discussion about this on one of the reflectors a while back
about
re-tubing the MLA with a less expensive tube. Can anybody give
me some
more information? Has anybody actually done this or know of
someone who
has? What would be a fair amount to pay for an MLA that needs
tubes?
Any suggestions would be appreciated. Thanks.
