Full Retube Kits for the Engl E840-50 Power Amps
The Engl E840-50 Power Amp. Every kit is configured to provide a specific sound/experience.
These are adjustable bias amps and all you need to check and adjust the bias is a bias probe and a Multimeter, or our all-in-one Eurotubes “Pro One” bias probe that reads both the plate current and the plate voltage simultaneously.
The default power tubes for these Retube Kits are the JJ 6L6GC’s. These tubes follow the classic 6L6GC sonic archetype with big lows, smooth mids and crystalline highs. What sets them apart is their low end clarity, mid-range detail and very clear highs without being overbearing or harsh.
Other 6L6 family options include the JJ 5881’s. The JJ 5881’s are a Classic 23 watt 5881 in a traditional stubby bottle. “Jangle” for days and a very warm full tone. Right in-between the JJ 6L6GC and the JJ 6V6S in power. If you’re looking for that early-breakup “tweed” era character these are it.
The Standard Retube Kit is as close to OEM as possible. Maintaining the amps stock level of headroom and gain while providing a warm but even handed overall sound. The kit includes one matched quad of JJ 6L6GC’s by default and Three Matched and Balanced JJ ECC83S’s.
The Gold Pin Retube Kit uses the JJ ECC83S Gold Pin variants to provide a smoother, creamier, and more singing overall sound. This option is less aggressive and has less “teeth” when driven hard. If you like a classic raunchy gritty overdriven tone, we recommend looking to the Standard or High Gain option. If sweet, open, and more refined is what you’re after this kit will do it. The kit includes one matched quad of JJ 6L6GC’s by default and three Matched and Balanced JJ Gold Pin ECC83S’s.
