PS Audio - BHK Preamplifier Tubes
Over time, tubes lose some of their life and can begin to sound dull. Under normal usage, you might notice these changes after one to two years. If you need a replacement pair or just want to have a back-up pair, we can provide you with a hand matched pair of tubes for your BHK amplifier or preamplifier.
