Matching tubes is necessary if closer to design limits, but Magnavox is usually tame enough on two good tubes, so this is a non-issue.
This amp is rated for 20 watts in Magnavox CR198 here http://www.nostalgiaair.org/PagesByM...5/M0010335.pdf

But 1947 sales literature I for the Berkeley stated 15 watts from the two speakers. Looking at Antique Electronic Supply website, a 5881 will work, listed for $26.

RCA or Ken Rad (GE) metal versions of 6L6, of which my 1948 Windsor has four, is rated 45 watts. These are more reasonably priced. https://www.ebay.com/itm/35423726914...Bk9SR-DLz7fbYA
My Unit has the CR-198E which I'm not sure if that makes any difference in the power rating department or not or how they used the 6L6s.

Also my Bass Control seems to make very little difference in adjusting the Bass Response on my unit, the Treble Control works great, and so does the tuning range response adjustment control built into the treble control, just the bass control seems to be non-functional, any ideas as to why the bass control is unresponsive?
