This is a kit of the famous Dumbleator, can be used as standalone device or for installation in an existing amplifier.

When build as a stand-alone device, the kit can be powered with the TT-VPump, in an amplifier the kit must be supplied via the existing power supply of the amp.

The Dumbleator offers numerous configuration options which are shown in the appended schematics.

Input Levels:
InA: 10-15 Vpp
InB: guitar level - 5 Vpp

The kit includes all the parts needed to build the "standard version" incl. a 12AX7, potentiometers and leads.
It does not include components that are required for the building the extended versions,  as well as a power supply or casing.

The Dumbleator utilize POTENTIALLY FATAL HIGH VOLTAGES.
Seek help from a competent technician if you are in any way unfamiliar with high voltage circuits.
Use at your own risk.

Kit for TT PSU Mini

The kit includes all components except a powertransformer and a choke for building PSU for tube amps. If you want to use a choke instead of the 5 W resistor than you must order the choke that you need separately.
The PSU can handle max 700 V DC at out B1 and B2, 450 V DC at out B3 and is recommended for tube amps up to 50 Watt. The size of the PSU is 97 x 55 mm only and has a high of ca. 40 mm.

Please refer the attached schematic for more infos about the layout and design of the PSU.

Tip: use Duncanamps' PSU Designer to simulate and calculate power supplies.

Kit of an active, serial tube-driven FX-Loop (with parallel option) for a subsequent installation in an existing tube amplifier
The FX-Loop works with one 6112 miniature tube in the send and in the return stage. The send and return level can be adjusted to their optimal value with two potentiometers. The Loop works with the present high voltage of the amplifier.
It has two inputs for low and high signal levels.

Input Levels:
InA: 30 - 60 Vpp, max. 65 Vpp
InB: 10 - 15 Vpp, max. 18 Vpp

Heater:
6,3 V @ 300 mA

The FX-Loop utilize POTENTIALLY FATAL HIGH VOLTAGES.
Seek help from a competent technician if you are in any way unfamiliar with high voltage circuits.
Use at your own risk.
