Especially for the GA-5 tube-amp constructed adapter to use a EL90 instead auf an EL84. The EL90 is a 6V6 but with a different pin-layout and glas-container and much smaller than a normal 6V6 which make the EL90 ideal for this kind of application.
THIS KIT IS NOT AVAILABLE ANYMORE.
The brother of the G-Force One but for Bass. Based upon a transistor-circuit and can also be used as a full preamp. The booster is build on PCB, it is simple and easy for beginners too. The kit includes all parts needed to build the booster, the schematic and the PCB layout. Not included: Knob for the potentiometer Chassis
About the chassis:
Double Relais Swithcer for channel switching and similar applications. The kits comes with all components incl. 6 V Finder relaise but without switched for the front panel. Works with 6,3 V heater voltage.
Ultra Linear Booster for Guitar, based upon a transistor-circuit. Can also be used as a full preamp. The booster is build on PCB, it is simple and easy for beginners too. The kit includes all parts needed to build the booster, the schematic and the PCB layout. Not included: Knob for the potentiometer Chassis
Active, serial FX-Loop for a subsequent installation in an existing tube amplifier The FX-Loop works with two LND150 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
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.
TT OPP Kit for building an OP Preamp, Buffer, Driver, Whatever... Please check the ->Project-Page<- for more infos and details
The kit comes with all components needed to build the preamp, like resistors, OP, capacitors, wires etc. but WITHOUT potentiometers, 6,3 mm Jacks and Housing because these items are not needed all the time, depending on the type of preamp that you want to build. Please see "Recommended Items" for Potentiometers and Jacks which can be used.
TT Power Attenuator PoS 100
Leistung / Power: 100 W Dämpfung / Damping: 0 - 100% Impedanz / impedance: 4, 8, 16 Ohm Line-Out
The PoS100 attenuator is the steady further development of the PoS50 and provides a simple construction and simple handling together with a high power rating. The Pos100 can be used with a load of 4, 8 or 16 ohm and has a maximum power rating of 100 W. Another addition is the available Line-Out which can be used to directly process the output signal. The attenuator gets build in a compact chassis of 2 mm aluminum plates. This kit comes with all items needed to build the PoS100, aluminum chassis, black faceplates, knobs, screws and schematic and layout.
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 !! 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.
Variable voltage control for voltages up to 600 V Possible applications: - G2 Control - Power adjustment Please see the -> TT VoCoM project page <- for more infos Kit includes: all parts to build this VVC. Resistors, Heatsink, Wires, Potentiometer, PCB, Label, Screws, Nuts. WARNING: HIGH VOLTAGE !! This kit is not for beginners. If you do not know what you are doing than you should NOT buy this kit!
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.
