We produce a few standardized format Rack pieces for the concerning studio and pro stage application.
Most of these units are tweaked and massaged in one way or another for the application and end user.
Preamplifiers, power amps, integrated power amps with onboard preamps, reverb units and all their varying iterations are pieced together by function for the slated task and the musician who'll use it.
These photos are representative of what is possible. While units are available exactly as seen feature for feature, they are fabricated entirely by hand on a case by case basis so having them made for you is advantageous. What you see is what someone else needed! We are currently trying to restore access to many many hundreds of build pictures and if we do get them back there will many more examples to look at.
If you're wondering what the big doughnut looking thing is, as it is quite often referred to in lines of questioning, it is the toroidal power transformer. This technology is far superior to standard linear transformer technology. These are extremely efficient and deliver impressive amounts of power per pound. They have electromagnetic noise properties that standard power transformers can only dream of. The vast majority of products produced by ChromeDomeAudio utilize toroidal power transformers. In this case the transformer is literally operated in halves. When only on channel of the power amp is on, power only flows to that side of the power supply board, to the tubes filaments, to the individual indicator lights. These components have dual heater supplies and dual high voltage supplies. The parallel/series operation of the primary means any product produced can naturally operate on 120Vac or 240Vac mains supply.
Compact 2U 30 wpc, 6L6 based (Can use EL34s) stereo tube power amplifier with onboard instrument preamplifier capable of driving both independent channels. Each channel is controlled by its own dedicated 3 position power/warm up/operate switch. It has power amp inputs located on the front and rear panels with independent gain/level controls.
The instrument preamp utilizes a simple Volume, Treble & Bass control topology with switchable functions controlled by Treble & Bass controls. These features make the amplifier as a whole capable of great big clean Guitar or Bass tone or larger then life vintage gain that is nothing but amplifier.
In this circumstance, the combination of instrument preamplifier with dual mono power amplifier makes this unit an effective instrument unto itself.
The rear panel handles mains supply power input via a standard IEC (Detachable) power receptacle and mains fusing, power amplifier inputs, dual speaker outputs, 2 per channel with 4/8/16 ohm output impedance capability and power tube fusing to disable output section in the event of a tube failure.
