S-meter circuit HQ-145
The circuit as designed is subject to significant drift.
Has anyone found a mod or knows of a link to a mod? I prefer NOT to get into matched 6BA6s. I am a retired EE and before I jump into the circuit I was wondering if someone jumped in ahead of me. |

6ba6 are notiorius for grid/cathode leakage and if your using a a high
impedence circuit that is compounded too , try 6ba6w they much better....P "Dave" wrote in message ... The circuit as designed is subject to significant drift.
