I have a similar tank, and this is one of only 2 circuits I've seen that uses a high input/output impedance tank with grounded input & output connectors. The other is the
Nonlinear Circuits Big Room Eurorack module (based on
Polyfusion VC Reverb). The high impedance of these tanks requires a lot of drive current, so they usually have higher voltage PSUs than more common lower-impedance tanks. So keep that in mind if you need to find a replacement PSU.
Here is the
decoded tank information:
Dynacord Spring Reverb Tank - #
4FB2A1C
Digit - Specification
1st -
Reverb Type - (4) - Type 4
2nd -
Input Impedance/DC Resistance - (F) - 1,475/200 Ohms
3rd -
Output Impedance/DC Resistance - (B) - 2,250 Ohms/200 Ohms
4th -
Decay - (2) - Medium (1.75 to 3.0 s)
5th -
Connectors - (A) - Input Grounded/Output Grounded
6th -
Locking Devices - (1) - No Lock
7th -
Mounting Plane - (C) - Vertical, Connectors Up
You can still find
replacement tanks if needed.
