All these schematics have been built by me and are thoroughly tested...

Single Ended monoblocks with AV325B ref powertube and interstage coupled AD8 driver. Dual power supply. So called "Koets von Bach" amplifier. |
|
Single Ended 2A3 or '45 amplifier with double 5Y3GT rectifier and 6SN7 as driver. |
|
"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 powe amplifier. Featuring the 50 and ECC32 (ECC32 can be replaced by 6SN7..). |
|
Push-pull design 6AS7(6080). Driver/phaseinverter is ECC82, 12BH7 long-tail. Plates of the latter are inverted connected to the UL-taps of the OPT's. |
|
The VaicVV45 preceded by the Ba in a mu-stage 12HG7!!! |
|
Same amp as previous one, only
simplified.No mu stage anymore for the Ba. |
|
The Top? the ER231 is the driver, interstage (Lundahl 1660) connected to the AVVT 2A3. Both having their own power supply. |
|
A copy of Bruce M Bermans homebrew
preamplifier, with adjusted tube choice. 56 and 6J5 are direct coupled,
kathode output. Both supply and amplifier are on separate chassis. |
|
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. |
|
L'audiophile at the top: Put the
shielding of your interlinks at negative potential using a battery. |
|
Update your mains! Cost effective
way to improve your mains supply. You'll be astonished with the results! |
