AMP-10 - 10W Tube Power Amp with Matching Power Supply


In Stock
Product Code:


AMP-10 is a 10W tube power amp with a matching power supply.

AMP-10 is comprised of two elements:

  • our PA66-10 Push-pull Power Amplifier using standard octal-based power tubes
  • plus our PSU-10 Super-quiet Power Supply for 10W Tube Amps

  • toroidal output transformer
  • toroidal power transformer
  • Japan-compatible 100-120-240V mains
  • uses 12A_7 for front-end
  • safe voltages for NOS tubes (320Vdc)

Note that if buying both kits (PA66-10 + PSU-10) separately, the cost  = $565, but the price of AMP-10 =  only $516  Save $49!

This amplifier can use any of the standard octal-based power tubes, or even mixes of tubes. The power supply provides all the voltages required for a tube power amp and preamp, along with auxiliary voltages for switching circuits or opamps.

See the detailed descriptions of the two kits:



Kits require assembly. If you would like this kit assembled, add PSU-BLT Assembly of Large Power Supply to have the power supply portion pre-assembled, and add PA-BLT Pre-Assembly of Power Amp to have the power amp portion pre-assembled. The transformer fly-leads will NOT be attached to the boards. The assembled boards are bulkier than the loose parts, so shipping is slightly higher.

AMP-10 can be combined with any London Power tube preamp kit (D-PRE, F-PRE, LP-PRE, M-PRE, S-PRE, V-PRE, Z-PRE), effects loop kit (BFX), and/or reverb kit (REV, REV-COMP) to create an integrated amp.

Add GND Ground-Link-Isolator to avoid ground loops with other mains-powered equipment.

Use two AMP-10s for stereo.
