Full Retube Kits for the Bad Cat Black Cat 40R amps
The Bad Cat Black Cat 40R Retube Kits.
All of our Bad Cat Black Cat 40R full Retube Kits are designed specifically for these amps. Every kit is configured to provide a specific sound/experience.
The default power tubes for all of our Bad Cat Black Cat 40R kits are the JJ E34L’s. Thru the years the JJ E34L’s with their added punch and articulation have become a favorite here at Eurotubes and with our customers. They are very tight with an extended low end over a standard EL34. However you can use the Power Tube drop down to select the JJ EL34’s, the JJ EL34II’s, the JJ KT77’s or the JJ 6CA7’s. The JJ EL34’s are known for their mid range bloom and have a slightly looser feel when compared to the E34L’s. The JJ EL34II’s are not as aggressive as the E34L, but they are a little fuller in the lows and low mids than the EL34’s. The JJ KT77’s have an extended frequency response with big/chunky lows (even deeper than the E34L’s) and chimey/present highs. The mids are very smooth for an EL34 type tube and when driven they’re extremely rich and complex. The JJ Big Bottle 6CA7’s have big lows (on par with the KT77’s), an emphasis in the lows mids, and very round/natural highs. This gives the tube a very thick and round character that’s as close to crossing a standard EL34 with a 6L6 as you can get.
These amps are cathode biased so the E34L’s, EL34 II’s, EL34’s, KT77’s and 6CA7’s are all plug and play.
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 pair of JJ E34L’s by default, one current Balanced ECC83S for (V7 closest to the power tubes), one JJ EF806 for V3, and five Standard JJ ECC83S’s for V1 – V2 – V4 – V5 – V6.
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 elsewhere… If sweet, open, and more refined is what you’re after this kit will do it. The kit includes one Matched pair of JJ E34L’s by default, one current Balanced Gold Pin ECC83S for (V7 closest to the power tubes), one Gold Pin JJ EF806 for V3, and five Standard Gold Pin JJ ECC83S’s for V1 – V2 – V4 – V5 – V6.

Sonically this setup is very similar to our Standard Retube Kit but with a little extra gain on tap. The kit includes one one Matched pair of JJ E34L’s by default, one current Balanced High Gain ECC83S for (V7 closest to the power tubes), one JJ EF806 for V3, two Standard High Gain JJ ECC83S’s, three Standard Handpicked High Gain JJ ECC83S’s for V1 – V2 – V4 and two Standard ECC83S’s for the verb in V5 – V6.
The SRV Option Retube Kit It’s no secret that Stevie played his amps cranked and preferred a little cleaner sound from the front end, allowing you to hear more power tube breakup. This kit uses a JJ 5751 for V1 which is in-between an ECC81 and an ECC83S in gain. The kit includes one Matched pair of JJ E34L’s by default, one current Balanced ECC83S for (V7 closest to the power tubes), one JJ EF806 for V3, four Standard ECC83S’s for V2 – V4 – V5 – V6 and one Standard JJ 5751 for V1.
