yes, It is a two-component adhesive, absorb vibration and keep the transformer fixed to the shell

Quangho: Using adhesive to contain transformer vibration is an intriguing idea! Does it work as well as you hoped? What exactly is the adhesive?

Regarding damping absorption of vibrations, it may be a better solution to use that kind of silicone (attached pic).

I can help you buy from China chasic, and can help you make the PCB, but I'm afraid the shipping costs will be very low! because it is very heavy.

you can refer to similar projects, but much cheaper!

Well it's taken about a year but I have finally "finished" my Leach Amp twins. I had the pleasure of taking Dr Leach's class about a decade ago and always had ambitions of building speakers and an amplifier to power them. Done and done.

The details:
  • Leach Amp v 4.5 boards powered by 500VA 40V+40V toroids.
  • ESP's Project 38 turns the amps on when a signal is detected.
  • In standby a "breathing ring" glows through the front driven by 555 timer.
  • Cases are custom with aluminum tops/bottoms and cherry veneer wrapped. Fortunately I had access to a waterjet to do all those vent holes.
For now I have one hooked up to the aforementioned speakers (RJB's Microbes) and the other will likely be hooked up to vintage 70 set that are currently being driven by a Pioneer SX-6000.

To do items are:
  • Improving the grounding--the heatsinks make contact with the lid which is grounded to the bottom, but I want separate wires for each for redundancy/safety.
  • Add proper fork terminals to the wires on the various terminal boards.
  • Tie down the various wires
But for now I'm enjoying the fruits of my first amp project.

A 6 channel preamp put together in an old BK Electronics MXF200 chassis. Uses one of those remote control ebay preamp modules using NE5532 opamps.
Has 3 channels of power amplification too (rear left and right plus centre channels) using one of the original 105w MXF200 modules plus 2 DIY ebay mosfet power amp pcbs to power rears. Sub and main front left and right got XLR connectors on the rear panel to goto crossover and main power amps.
