6V AC-DC Linear Power Supply, 1400mA (1.4A), Positive Center | PV-61P
The PV-61P is a heavy-duty, traditional AC-DC linear power supply providing a stable 6VDC output at a maximum current of 1400mA (1.4A). Built as a robust, non-regulated transformer block, it delivers exceptional reliability and low-noise electrical performance for compatible electronic devices, project enclosures, and OEM vintage gear.
Key Features & Specifications:
- Linear & Non-Regulated Design: Utilizing a classic copper-wound transformer design, this unit provides raw, durable linear power. Note: As a non-regulated power supply, the output voltage will naturally sit higher than 6V under no-load conditions, stabilizing accurately at 6VDC once it reaches its nominal 1400mA load.
- Output Performance: 6VDC @ 1400mA (1.4 Amp max continuous output).
- Input Voltage: Standard 120VAC, 60Hz domestic input configuration.
- DC Plug & Polarity: Terminated with a standard 2.1mm x 5.5mm barrel plug featuring a strict Center-Positive ( + ) polarity configuration.
Typical Technical Applications:
- Vintage & Retro Electronics: Replacement transformer for legacy electronic gear, older consumer electronics, and specialized toys built specifically for unregulated, center-positive 6V power.
- Audio & Radio Gear: Because linear power supplies do not use high-frequency switching circuits, they generate minimal Radio Frequency Interference (RFI), making this model well suited to vintage AM/FM radios, legacy audio pre-amps, and signal processing hardware.
- Laboratory & DIY Testing: A dependable component for electrical engineering benches, custom hobby projects, and school laboratories requiring traditional unregulated DC power curves.
Important Compatibility Notes:
- Polarity Warning: This adapter is strictly Center-Positive ( + ). Double-check your device's power port requirements before purchasing, as using this adapter with a center-negative device can cause damage.

Frequently Asked Questions
Q: What plug size and polarity does the PV-61P use?
A: Standard 2.1mm inner diameter x 5.5mm outer diameter barrel plug with center-positive (+) polarity. The inner pin carries positive 6V and the outer sleeve is negative.
Q: What is the difference between the PV-61P and the PV-61A?
A: Polarity only. Both are 6VDC 1400mA non-regulated linear supplies with a 2.1mm x 5.5mm plug. The PV-61P is center-positive (+), while the PV-61A is center-negative (-).
Q: Why does my meter read more than 6V with nothing plugged in?
A: That is normal for a non-regulated linear supply. Output voltage sits above 6V under no load and settles to nominal 6VDC as the load approaches its rated 1400mA.
Q: Why choose a linear supply instead of a switching supply?
A: Linear supplies use a copper-wound transformer rather than high-frequency switching circuits, generating minimal radio frequency interference (RFI). This makes them ideal for vintage AM/FM radios, audio pre-amps, and sensitive RF gear.
Q: Can I use this on a device that draws less than 1400mA?
A: Yes. Devices draw only the current they need. However, because this is an unregulated supply, a lightly loaded device will run slightly above 6V, so verify your device's voltage tolerance.
Q: Will this work on 220β240V power outside North America?
A: No. The PV-61P is built for standard 120VAC 60Hz domestic wall power only.
Q: What happens if I use the wrong polarity?
A: Reversed polarity can damage connected equipment. Always match your device's polarity symbol to the center-positive marking on this supply before plugging in.
