100W Guitar Amp Upgrade Kit B.

This valve kit consists of four x EL34-B uprated power valves and three 12AX7B low noise valves for the preamp and driver positions.


This kit is the perfect solution to upgrading and reviving classic 100W guitar amps from Marshall, Blackstar, Laney, Peavey, Koch Amps and any other head or combo based on these valves.

 This is an ideal upgrade replacement set of output valves for Marshall models: EL34 100/100 (2 quads will be needed), EL34 50/50, JCM800 (100W), JCM900 & JCM900 SL-X (100W) EL34 version, JMP100W EL34 version, JVM 210C, JVM210H, JVM410C, JVM410H, Lead / Super Lead EL34 version, Handwired 1959HW and any other guitar amp using four EL34s as output valves including the Blackstar HT Stage 100, Laney GH100L, Peavey 6534+, Peavey Windsor 100W and the Koch Amps Supernova 6060.

Shuguang EL34-B Valves will be supplied in this kit, with a higher maximum anode/plate power dissipation (up from 25W to 30W per valve) so this means you can push your amp harder without "red plating" your output valves.

The Shuguang 12AX7B supplied in these kits offers even lower noise than the 12AX7A, but with the same high gain figure for a bigger sound with less hiss!

Offered at a fantastic price of just 72.99!
