A new Revalverb unit is ready ! I finished building it last week.
I just made 2 videos as an example below . No EQ , Comp , gate or something added to the reverb . It s the raw sound of the unit. MP me if you need wav files

The input level is set to 1/4 on this exemple . The master volume at 1/2 . The unit have a big headroom ! This spring reverb just have a clean hiss , no buzz , hum or strange noise ( exept the swith "pop" , but it s normal and generally we don't use them in "live" . We set the sound before in studio.

Of course the choice of tank is essential to find the desired final color . There is a lot of choice . That why i will always use Spring reverb with external tank . Less noise , more choice :) !

- 4 Tubes ( Line In Preamp / Driver / Recovery / Line Out )

- 4 transformers ( Toroid with Shield for PSU , Transformer In /
Transformer Out and Hammond Driver transformer )

- HPF 5 positions on signal input ( Before the Spring )

- HPF 5 positions on signal Output ( After the Spring )

- Bias switch ( clean / Warm ), " Boost" switch for the wet signal , Drive , Line input and master volume

DEMOS :
Tank 1 ( short Decay MOD 4AB1C1B ) : https://www.youtube.com/watch?v=4J2-vZFJsOA
Tank 2 : ( Long Decay TAD4AB3C1B ) : https://www.youtube.com/watch?v=75gvAdxha14

Fisher K10 Space Expander revisited !

I use the same circuit to drive the spring ( and real transformer used in fisher K10 ) but i add :

- Real balanced ( with transformer ) line + preamp in front of driver
- Real balanced line output ( Tube stage SRPP + transformer )
- HPF 2 ways on input before the spring ( create a bass boost )
- HPF 2 ways on output after recovery amp ( bass boost )
- New PSU with active choke ( for Europe / 230VAC )
- Star ground design

All metal film resistors and capacitors to remove a LOT of noise , in fact it s 100% new unit but with the flavor of Fisher

I sell it with 3 tanks ( long / medium / short )
4FB/ 9FB /8FB
If you have already real Fisher tank it s offcourse 100% compatible
The unit is punchy, no noisy and perfect for studio use

I will make a video + audio from the mixing desk asap

Acually I just make a little video with my phone in the "lab" 🙂 :

Greetings !

Another valve spring reverb almost ready 😱

Yes , i spend my day beetween filter and Spring build . I like it , especially when they work at first start up 👌

This one is "different " because it s the modern version of Fisher K10, so yes this preamp accept the same tanks with high impedance input ( 4FB / 4EB / 9FB / 9EB )

The circuit is a pentode / triode in one tube 6BM8 tube . It s call direct coupled version of driver , SRPP stage for line output and fet/ mofset cascode circuit for reverb wet amplifier.
Why again another circuit ?
Because i have a lot of parts here in the lab and build "on vibe" 🙂
Sound is really powerfull ...
The test is always the same
When i hit the spring with fingers , i need to hear the same volume when use the aux send
That wat the noise is really down and the circuit like it need to.

Potentiometer in faceplate are input volume , tone and output volume . I will just add a toogle to control the bass response send to the driver and it s finish !

thanks for reading
