Upgrade your NVA P90 passive preamplifier

Upgrade your NVA P90 passive preamplifier to MKII P90SA specification:

  • Superb new stepped attenuators - quiet between steps (no cracking or fluffing), exceptionally smooth operation (no clunky clicks between steps) plus upgraded load resistors.
  • Upgraded silver plated internal wiring.

Ship your item to us.  We’ll send you full instructions once we’ve received your payment. If you're unsure what mark / model your existing amplifier is, and if it can be upgraded, please don't hesitate to contact us.

Upgrades are non-returnable / non-refundable. We will return your original attenuator(s) to you with your upgraded item (or dispose of, at your request).
