[AMPS] Rebuilding an MLA2500

[yo3ctk]

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.

	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.
