The Blackjack-21™ The BlackJack-21 is a single channel non master style amp with a more rock and roll attitude than the Fuchs ODS and TDS amps. This new series of amps offers that rock and roll tone and attitude in varying power levels. All models share a similar “in your face” attitude, at different power levels.
The Blackjack 21® is based on a dual 12AX7 preamp stage and a push-pull dual 6V6 fixed bias output stage. Unlike other amps in this price range, the Blackjack 21® has a full complement of extremely flexible tone controls. A liberal amount of clean headroom is available before the output stage begins distorting with a sweet yet cutting rock edge. Voiced like its siblings the Train 45® and Lucky 7®, the Blackjack 21® has a classic rock voice similar to a vintage Marshall or Trainwreck™ style amp, but with a more manageable power level. Its tone provides a cutting rock edge, filled with harmonic richness and chime. The circuit design also is “attenuator friendly”. The Blackjack 21™ has a preamp stage designed to allow clean-to-mean from the guitar volume control.
The chassis (like all Fuchs® products) is aircraft grade aluminum, our internal construction is mixed PC board and hard wired. On the Blackjack 21®, the preamp tubes and power supply circuitry are on the circuit card, while the power tubes and transformers are mounted directly on the chassis. A detachable power cord is standard. By using single point grounding, the amp is quiet and free of hum at all operating levels.

Jul 23, 2014 Just got a fuchs ods: best amp ever? Discussion in 'Other Amps' started by usablefiber, Jun 2, 2014. I have both Lucky 7 and Train45. The tone is so articulate and immediate, I sometimes shake my head in disbelief. I just listen to my friend crank up a Lucky Blackjack 21 full blast.

Introduction
Lucky Lucky is a side bet based on the player's first two cards and the dealer's up card. As far as I know, it is the first side bet to be based on the player's first two cards and the dealer's up card. Since it came out, there have been many imitators.
Through the years I have seen four pay tables, which I refer to on this page as numbers 1 to 4. Pay table 1 was the original one and seen at casinos all over the United States and Canada. Pay table 2 was a double-deck version, omitting the pay for a suited 7-7-7, which is impossible in a double-deck game. Pay table 3 came along around 2014 as an apparent effort to increase what was a low house advantage for a side bet. Pay table 4 can be found at Internet casinos using Felt Gaming software.
The following table shows the various pay tables.
- The Blackjack 21®-II and its siblings the 4-Aces®, Lucky-7®-II and Full House®-50 have a preamp stage inspired by our ODS® and TDS® designs, which allow clean-to-mean from the guitar volume.
- The Fuchs® Casino Series The Fuchs® Casino Series delivers the great Fuchs® ODS® style tones that built our business, to a more affordable format. While sharing circuit DNA with our ODS®/TDS® series, a simpler construction style and more basic feature set allow us to bring these same great tones to the working professi.
