UralTone 5F1 Nos Toaster Tweed kit - Documentation and Downloads

UralTone 5F1 "Nos Toaster" is a further development of the UralTone 5F1 v2.0 kit. The idea behind the design of the kit is, on one hand, to lower the price of the kit by using tubes other than traditional guitar amplifier tubes, while still maintaining or even exceeding the sound quality factors.

There is currently no illustrated step-by-step guide for the 5F1 Nos Toaster kit built into the Champ 2.0 chassis, unlike other UralTone kits. The NOS Toaster is electrically very similar to the 5F1 2.0, and aside from the power transformer, rectifier tube, and the preamp heater wiring, the build process is carried out in the same way as with the Champ 2.0 kit.

The kit is assembled using the layout diagram and parts list, which can be found via the links below. In addition, the page also includes the original 5F1 schematic and layout diagram.

Measurement Instructions

UralTone 5F1 Nos Toaster can be modified to use choke as we do with the 5F1 2.0 Champ. This modification removes the small hum 5F1 circuit has. On below link to choke version layout:

Aside the choke, eg: https://en.uraltone.com/choke-3h-120ma.html, additional axial capacitor of 10uF/450V is needed.
