The Audio Research AR D125 power amplifier uses:
8 x 6550 matched power valves/power tubes.
AR say that the valves should last about 2,000 and should be replaced with two x matched sets of four 6550 making eight valves in total. We sell them as matched quads so you will need to order two sets if you want to replace all the valves.
We always recommend JJ valves for this amplifier. This is because they guarantee you get awesome tone and long life and they don’t cost a fortune.
Remember, JJ is one of only five manufacturers in the world. So don’t pay higher prices for valves from the same factory that have simply been rebranded by other companies.
So restore the tone, the power and the sparkle to your guitar amplifier. Treat yourself to a brand new set of valves today.
