Turret Board – Tube Stage Prototyping Platform DOUBLE

Description

Build and audition tube circuits the fast, classic way. This turret board is designed for tube-stage prototyping and small, fixed builds. It’s available in two versions: for one or two UTM25XX input transformers. A Noval (9-pin) tube socket is onboard, compatible with the ECC83/12AX7/5751/12AT7/12AU7 and 6N1P, 6N2P families.

Highlights

• Rapid prototyping: Hand-wire components on robust turrets – no fragile breadboards.

• Transformer-ready: Choose 1× or 2× UTM25XX input transformer footprint.

• Onboard tube socket: Noval (9-pin) with proper pad layout and clearance.

• Clean grounding options: Dedicated pads for quiet star-ground routing.

• Flexible I/O: Clearly labeled pads for input, output, B+, heater, and ground.

• Sturdy build: Thick FR-4, heavy copper, plated-through holes, heat-resistant mask.

Typical Uses

• First gain stage / line buffer

• Transformer-coupled input tests

• RIAA / tone-stage experiments

• Small fixed builds for pedals or studio tools

Compatibility

• Tubes: ECC83/12AX7, 5751, 12AT7, 12AU7, 12AY7, 6N2P/6N1P (and other Noval-pinouts).

• Transformers: UTM 25XX series (select 1-transformer or 2-transformer version).

Possible Connections

• B+ (high voltage), GND, Heater 6.3 V, IN, OUT, Transformer prim/sec pads, star-ground point.

What’s included

• Turret board PCB with mounted turrets

• Noval (9-pin) tube socket

• Standoffs & screws (mounting kit)

Note: Transformers and vacuum tube are not included.
