A display of Some of my Amps:
Amp-oN Custom JTM 45
I build this amp after repairing a 1963 original JTM45. The Amp is build with vintage type Nos quality components including a 90's genuine Drake 6k6 output transformer with the specks to be so close in tone to the original JTM45 as possible.
Nothing has been spared here; the amp is fitted with Nos RFT – Mullard miniwatt tubes etc. Top-quality audio potentiometers, hand-built turret board with pio/silver mica capacitors and carbon compound etc, as in the original amp. 2 mods have been added - a line-out and an NFB regulation -(negative feedback in the power stage)
This doesn't change the amp's tonal qualities, it simply provides an option for recording or connecting to a P.A. through a line-out - and NFB is an additional option to control the amp's drive/tone.
Info :
The Amp has engraved front covered with plexiglass.
Front :
Standby sw – Main sw –Pilot lamp – Presence – Bass – Middle – Treble - Volume 1 – Volume 2 – Input 1 – Input 2 Hi/Lo
Back :
Line out – Variabel NFB –Speaker outputs – Ohm selector – HT fuse – Main power input with 1,6A main fuse
A completely unique and fantastic amp in a class of its own that delivers tones like that original amp from 1963. it doesn't get better than this.....

Amp-oN Custom Express v.2
This is Amp-oN´s special version of a Trainwreck Express Amp.
Inspired by TWE I built this special version with Amp-on mods which give the musician more options to control the volume and tone of this amazing Amp.
Info :
The Amp is based on a 6.6K Ohm output transformer (Classic Tone) from the USA.
Tubes :
It has 2 Nos Mullard xf2 EL34 outlet tube and 3 Nos preamp tube - Mullard 12ax7,
Amperex bugle boy 12ax7 and a Phillips miniwatt 12ax7 as in the original TWE amp.
It has a hand-built turret board with quality components such as coal compound resistors, PIO (paper in oil) - silver/mica capacitors, top-quality audio potentiometers etc.
Amp-oN variations on a classic TWE :
A low cut/boost in the first (Mullard) triode stage, a variable gain in second (mullard) triode stage,
A switch/triode selection option in the second tube stage (amperex) as well as a variable NFB in the phase splitter, which allows the user to vary the gain/drive in the output stage.
These modifications does not compromise the sound of the amp, they just offer the musician more options to control drive, tone and gain in the Amp,
Front operation:
Input - Low cut/boost switch - Volume - Trebble - Middle - Bass - Variable Gain - Presence.
Main switch - Pilot lamp - Standby switch.
Rear operation:
Main power/fuse - HT fuse - Ohm selector - Variable NFB - Speaker outputs - Triode switch.
The cabinet is handmade in Oak wood and finished with layers of ships-laquer.
So this is a uncompromising amp, fantastic both in terms of quality of the finish and design as well as sound and tone. It's dynamic and vibrant.

Amp-oN Custom Old Style Voxi 15
This is a custom-build topamp inspired by Vox AC15 and Marshalls 18 watt combo.
The first pre-amp stage is based on a EF86 pentode witch is switchable between pentode og triode mode with a switch placed next to the inputs. The tonestack is driven by a chatode follower stage and the powerstage is driven by a longtale phasesplitter.
The powertubes is 2 Nos EL84 and the HT powersuply is run by a Nos EZ81 rectifier tube.
The powersuply has a rectifier/diode switch so that the HT runs either on the rectifier tube or diodes.
With the rectifier the amp delivers 12 watts and has the rectifiers compression when it works at top volume. With the diodes the amp delivers 15 watt and has a more controlled and firm sound.
The output stage has a variable NFB mod consisting of a potentiometer and an on/off switch. This can alter the Amp´s drive... ( NFB = negative feedback )
Info :
Front operation :
Hi/lo inputs - Pentode / Tiode switch - Volume - Middle - Bass - NFB on/off -
Pilot lamp - Main power switch.
Back side operation :
Main power input/fuse - Rectifier/diode switch - Variable NFB - Speaker inputs - Line out.
