Schematics These schematics are from a library I have been compiling for years. Look for the ones marked 'TESTED'; they are plans I have personally built and tested. Only unique design and good performers are posted here. Enjoy! |

Amplifiers | Single-Ended |
|||
| Pre-Amplifiers | |||
| XFMR coupled pre-amp with balanced output - Tube rectifier, DC heated filaments - Interesting LCR eq circuitry and battery biasing |  |
||
| Preamp with xfmr coupled input - Discrete regulator for each stage of amplification - RC equalized network - Should be a good performer |  |
||
| Preamp with EF86 phono input stage - 12AU7 line amplifier - 6X4 rectifier |  |
||
| 6DJ8 line amp with EF86 phono input - Tube rectifier |  |
||
| 6DJ8 Line amp - 6DJ8 phono amp - Looks like a good performer |  |
||
| Moving magnet phono stage - Passive RIAA eq |  |
||
| 12AU7 line amp with xfmr coupled output - SS rectification |  |
||
| Jadis preamp - Pretty basic - One stage of gain |  |
||
| Interesting MM phono stage - Should be fairly quiet with paralleled triodes |  |
||
| Tested 6SN7 line stage preamp - Very good performance - Very neutral |  |
||
| Exotic line stage preamp using the 6C33C-B! - Looks like an overkill - Pulling 500mA from the power supply, this monster will drive any load and any length patch cable - Should perform well |  |
||
| Tested Very good performer - SRPP Line stage using the 5687 |  |
