"Power"-amplifier with
the 31 as driver. Very good sounding, not much power though.... |
|
A powerfull amplifier with the 807 in push-pull configuration and the ECC82 as driver/phase inverter. Diode rectified. |
|
Nice single ended design, with a SRPP 6SL7 as driver, MKP's powersupply and tube-recitfied. Loads of tube sound for a small budget. |
|
Power amplifier featuring the 300B. Mu-stage driver (6SN7/6888). |

Same amplifier as previous one, now perfected with a separate power-supply for both the driver and 300B. Driver is the mu stage 7788(E810F)/British MH4. |
|
Hefty power amplifier featuring
two old tubes: 227 and 250! DC-coupled, supply rectified by two halfway
rectifiers with choke input. The 227 is chokeloaded and DC-coupled to the
250. |
|
Superbly sounding all DC-coupled design power amplifier. Featuring the 50 and ECC32 (ECC32 can be replaced by 6SN7..). |

Pre amplifier with the 5687 using a line-out transformer. A real good one! |
|
A complete pre-amp with stabilised power supply using only 3 6SN7's? Take a look! |
|
Kick-ass preamp!If you don't have
to drive long cables (>50cm), this is the way to go. Choke loaded 227. |
|
Need low-impedance? This 37 in
a mu stage 6CH6 and stabilised power supply does the trick. |
|
Guitar amplifier. One input, ECC82
iput, tone-control/defeat, ECC81 phase inverter and push-pull EL34. |
