These Ampeg pre amp revalve kits are put together to provide a sonic upgrade over the stock valves in your Ampeg. I own and have played over the past 30 years Ampeg SVT, Original V4B and for recording the B15-N portaflex. I have also used many of the Ampeg valve pre amps.So these kits use the best of New Old Stock valves and modern day production items to give you the best sound out of these lengendary bass amps.
Ampeg SVT 3 Pro Philips U.S.A Pre amp kit is designed to give your SVT 3 Pro a clean sound but with more upper end attack whist retaining a warm midrange emphasis. This set will suit the player who wants to get the best of both worlds in terms a combination more of a vintage valve sound and more modern high end attack.

The Military grade JAN specification 12AX7WA Philips is one of the best types I have personally found in bass guitar preamps and bass heads that I have used over the years.

The main feature is its clear and solid bass response which has a smoother and more defined sound then any modern made 12AX7. The valve is also very well balanced
with a slight midrange emphasis, but not as pronounced as the Harma ECC83 Retro.
The real strong point is the valve smooth high end attack as it supplies plenty of punch without the hard end splash of many other 12AX7 types.

The Philips Jan Military Specification ECC82/5814A was made with the highest grade materials and with no compromise on selection or quality control as they were for the American Government. These valves have a number of unique features such as high grade filament isolation so even after long periods of use the filament will not degrade. Immune to shock and vibration and were also rated for long life. The 5814A has a very clear bass response, which is both tight and musical. The sound is well balanced and good even detail across the audio spectrum with a clear and smooth treble. The sound and build quality is not equalled by any modern day valve. That is why it is used in this kit

The valves when used in conjunction with the extensive tonal shaping of the SVT 3 pro can be used to get the full range of modern clean, funk sounds right through to a big warm rock sounds.

The kit consists of 5 valves
