AMP-25 - 25W Tube Power Amp With Matching Power Supply

AMP-25 is a 25W tube power amp with a matching power supply.

AMP-25 is comprised of two elements:

• PA66-25 push-pull power amp using standard octal-based power tubes
• PSU-25 Super-quiet power supply for 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 (420Vdc)

Buying both kits separately  - $626

AMP-25 price - $564

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:

PA66-25

PSU-25

Kit requires assembly. If you would like this kit assembled, add PSU-BLT to have the power supply portion pre-assembled, and add PA-BLT 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-25 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 have an integrated amp.

Use two AMP-25s for stereo.
