Tube Store

At Sharp Sounds we have in stock a range of tubes to suit most guitar and Hi-Fi amplifiers


All our tubes are tested and matched prior to fitting in your amp using our

AMPLITREX AT1000 tube tester.

Yellow Jacket Power Reducers:

These devices reduce the power of a 50watt amp to a 15 watt, or a 100watt amp
to a 60 watter. Don’t trade your overpowered beast in, convert it – cheaper!
Just let us know the make and model of the amp you want to convert and
we can supply the correct Yellow Jackets.

Full range of Yellow Jacket Power Reducers available:


Tubes are consumables and as such are not covered by warranty unless otherwise
specified, however tubes D.O.A will be replaced. All tubes sold and/or fitted by
Sharp Sounds are tested beforehand using an AMPLITREX ‘AT 1000’ digital tube tester.
