Selling a Downbeat custom built clone of the RCA BA-2B / BA-2C tube microphone preamp. We’ve built around 10 of these units so far and love them at the studio.
This is a brand new build leveraging new old stock tubes, vintage transformers and VU meter. The unit is built to the original schematic with modern resistors, capacitors, switches and pots. External power supply for lower noise. The preamp and power supply are built into a pair of Bud Industries Portacab enclosures.
Features:
- NOS Matched Pair of GE 6J7 tubes
- NOS RCA 6X5 power Tube
- NOS ADC mic input transformer and Collins branded UTC output transformer
- DI input switchable via push button switch on rear of unit
- NOS Weston VU/Decibel meter - switchable in/out of circuit
- New Fairchild style knobs
- Four step switchable input pad -40db to 0
- Variable gain control
- External power supply with tube rectifier and new Hammond power transformer
- DC Volt meter to monitor B+ tube voltage
- 5 pin XLR cable for power supply
- IEC power cable
We are happy to run stems through the unit if you want to get a feel for the sound. The meter does add additional harmonic distortion when switched in, which is why we added the ability to have it in or out of the circuit.
We will remove tubes for shipping and include original branded tube boxes.
Please let us know if you have any questions.
