| The two 803 Tubes for feedback circute. | [picture follows] |
 |
The small, but very important parts of circute... I“ll check them for correct values. |
| Firtsable the plate filter cap (C1). should be: 0,95µF is: 0,92µF |
 |
 |
The primary cap, which is constructed as an MMC (C2) should: 3nF is: 2,88nF |
| The filament filter cap, which is an FKP-1-2000, too. (C3) should: 1nF is: 960pF |
 |
 |
The grid cap, which is constructed as an MMC (C4) should: 1,3nF is: 1,3nF ;o) |
| The grid resistors should have 2,33kΩ and is 2,34kΩ. |
 |
 |
The Potentiometer to set the whole resistence should have 4,7kΩ and has 4,78kΩ. |
| The current of one tube... |
