These Ampeg full revalve kits are put together to provide a sonic upgrade to your Ampeg. I own and have played over the past 30 years Ampeg SVT, Original V4B and for recording used the B15-N portaflex.These amps are still the kings of bass amplifier in my opinion and 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 Vintage Reissue Classic Retro full upgrade kit is designed to give you the warm and growling sound of the original SVT. The ECC83 Retro has a clean sound but with more emphasis on the midrange. This set will suit the player who wants a full range of vintage ampeg sounds right through to a modern clean sound with that big warm and growling bass sound.

The Harma ECC83 Retro provides a harmonically rich and detailed sound with excellent 3 dimension midrange response. This valve has a traditional British voiced with the outstanding feature of it's smooth linear midrange response and extended frequency response so you get smooth warm midrange, Excellent clarity and tight fat punchy lows. This captures that classic vintage Ampeg bass sound better than all the other ECC83/12AX7 that I have tried.

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 Harma 6550A Retro is designed on the classic General Electric 6550A that is regarded as one of the best 6550A types made. The valve uses special thick mica with internal bracing and spacing supports with full length anode heat wings to aid cooling capacity and provide improved heat transfer. The plate is constructed out of high temperature laminated alloy with an industrial grade glass envelope to prevent microphoney. The control grid wire is made of gold with a special coated screen grid to improve reliability. The combination of these features supply a deep solid bass response with even balance a great high frequency detail. This valve supplies exceptional midrange clarity with plenty of high end definition. The bass has a deep punch and is ideal in The Ampeg SVT Models giving the amplifier a true vintage voice. This is the best current production 6550A and gives the sound you would expect from a high grade bass amp.
