organdonor amplification ODB800 100 watt model

organdonor amplification ODB800 2203 custom 100 watt lead model modified JCM800 superlead circuit

The ODB800 is a custom hand built circuit based off the classic 1980’s designs customized and tailored to sound simply incredible through a 4×12 cabinet.  The amp is built with high quality components such as magnetic components 100 watt transformers and choke, F&T filter capacitors made in Germany, Dearborn paper n oil coupling capacitors, passive send/return effects loop, external bias pot and rear mounted bias ports, jubilee knobs, turret board construction using tolerance tested resistors, Cliff jacks and Alpha pots.  Matched set of your choice of EL34/6CA7/KT77 output tubes and vintage ECC83 Mullard and Raytheon preamp tubes.

Outer Chassis Dimensions: 26-1/2″ (Length including wings) x 6-1/2″ (W) x 2-1/2″ (D).
Chassis fits standard JCM800 head cabinets.

This is an impressive 100 watt lead amp and nails the iconic tone so many guitarists have been seeking and continue to be inspired by to this day.    

It is considered a “hot” amplifier because it has more gain stages than comparable amplifiers, and in “lead” mode (in the “high” input), an extra triode provides extra gain to the pre-amplifier, which “made for one hot rock amp”

Preamp tubes: three ECC83.
Output tubes: four EL34.
Rectifier: solidstate
Controls: Pre-Amp Volume, Master Volume, Treble, Middle, Bass, Presence.
Output: approximately 100 watts RMS.

Custom head cabinets available upon request.

organdonor amplification Lungster 10 model guitar amp

 

 

https://reverb.com/item/3148364-organdonor-amplification-lungster-10-watt-all-tube-guitar-amp-ecl86-ez81

The Lungster 10 is built from a 1960’s Hammond organ power amp chassis completely converted into an all tube guitar amp.  This is a custom hand built circuit with volume (gain) and tone.  The amp’s foundation is a high quality Hammond power transformer and output transformer.  Built with carbon composition resistors, new and original tone circuit components and constructed point to point with terminal strips.

Amp produces dynamic touch sensitive cleans and is very smooth producing moderate break up with volume up.  The ultimate small amp effect pedal platform with articulate sonic clarity so that nothing stands in the way of the guitar and effect tone.

Power section utilizes the EZ81 rectifier tube.  Cathode bias push-pull output section with a pair of ECL86 output /preamp tubes producing a modest 10 watts output power.  Completely tested chassis ready to be mounted in your own head or combo cabinet.

organdonor amplification JTM50 custom vintage 50 watt

 

 

The amp’s foundation is powered by a vintage 1960’s paper bobbin Wurlitzer organ amp power transformer, new Classictone 50 watt Marshall style output transformer made in USA and a new New Sensor Corp. 8H choke. Built with new and vintage tolerance tested circuit components. New F+T power supply capacitors and vintage tolerance tested carbon composition 1/2 watt resistors, metal film resistors, new mylar coupling capacitors with components built on new turret board. 2 amp mains fuse, 1 amp high tension fuse, vintage white pilot light, new silver Marshall style knobs, heavy duty vintage power and standby switch, hi and lo inputs for normal ch.1 volume and bright ch.2 volume, treble, mid, bass, presence, cliff style input & output jacks, 4,8,16 ohm speaker outs, alpha audio pots.
Top mounted mojotone black n white custom Marshall style head cabinet.

Amp produces very smooth, articulate and detailed cleans at low volume. When pushed, breaks up into a classic gain structure sound that’s definitely very classic Jmp/Jtm marshall. Full and balanced, with superb note clarity even when pushed into breakup. This is a non-master volume amp.

This amp is built with a top chassis mounted 50k ohm bias pot for using different output tubes such as EL34/6CA7/KT77

Including a used tested set of 3 x 12AX7/ECC83 preamp tubes and tested and matched ValveArt EL34Ls with the amp. The ValveArt tubes sound excellent!
Amp comes with a vintage high quality 5U4GB rectifier tube.
Buyer can choose either solid state plug in rectifier or tube 5U4GB/5AR4-GZ34 rectifier.
