Black Star guitar amplifiers have quite rightly caused a major buzz in the music industry since their launch back in 2007. By upgrading the valves to our selected sets customers have been able to voice their amps to their personal requirements. Customers have reported a range of benefits when upgrading the valves over the factory items. Here we have listed our most common upgrades using current production and the best new old stock items to help you get the most out of these fine Black Star amplifiers.
This Classic upgrade kit covers the Black Star HT1, HT1-R combos and HT1-R head and is designed to provide the ideal combination for those who demand a tight driving rock sound with plenty of rich sustain. It is an effective upgrade over the stock valves for those who want a more authentic rock and blues sound.

We use a combination of the best of the current production and new old stock items to achieve this.

The Harma ECC83 Retro provides a harmonically rich and detailed sound with excellent 3D midrange warmth. This valve has a traditional British voiced sound that has a huge singing sustaining tone when overdriven. The outstanding feature of this valve is its smooth linear midrange response and extended frequency response so you get smooth warm overdrive with tight fat punchy lows.

Black star uses an ECC82 as the output valve and in this kit we use the new old stock Philips ECC82-5814A for very good reason.
The Philips Jan Military ECC82-5814A is used as it is a special military grade valve that was with the highest grade materials and with no compromise on selection or quality control as they were for the American Government to be used in avionics. 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. The 5814A were designed to be immune to shock and vibration as they were designed for military aircraft and they were also rated for long life. To put it simply, no modern day ECC82 is made to this specification and no modern day ECC82 sounds like it. The Philips overdrives very evenly and does not fall apart when you saturate the amplifier.

The 5814A improves the amplifier as it losses the grainy unmusical fuzz that is displayed by many modern ECC82 in the black star. This valve has outperformed many more expensive ECC82 and therefore we have used it in this kit.

The kit consists of
1 Specially Selected Harma ECC83 Retro
1 Specially Selected Philips ECC82-5814A

Please note that the kit is for the valves only.
