Manley Snapper Monoblocks Review
October 7, 2021 § Leave a comment
One more thing worthy of note, while some tube amps these days support an auto-bias configuration, the Snappers need to be biased manually. Manley provides excellent instructions in the owner’s manual and on their website -it’s not that tough. They are even kind enough to include a basic digital multimeter (DMM) so you won’t have to source one. Usually, biasing power tubes needs to be done when they are new, again at about 100 hours, and maybe double check every few hundred hours. Somewhere down the road, one or more of the output tubes will no longer bias up, or you’ll notice a bit of softness in the high frequencies. That’s when it’s time for new tubes. Unless you’re made of money, work with the standard tubes. Rolling EL-34s these days is expensive.
