Great replacement for the original Phillips in the silver face Vibro Champ. Late Breakup lets the tubes get into saturation while still having good touch sensitivity. Nice tone without modifying the amp.

Picked up a White model 80 amp at a swapmeet, it had tubes in the wrong sockets and a junky no-name modern speaker. Didn't know quite what it was at the time, but figured anything made in Fullerton might have a Fender link. I replaced the filter caps (saving the old ones) and installed tubes from my NOS stash. The final touch was ordering a Jensen P8R speaker. It's a great-sounding amp for harp, lap steel, and my Oscar Schmidt electric dobro.

The P8R is the bee's knees. I replaced the thing in the Bugera BC-15 with the P8R and I am one happy camper.

Found a Champ for five bucks at a garage sale that was pretty beat up. I did a complete cap job, put in a JJ 6V6 and a Jensen P8R. This amp now sounds fantastic.
