Peavey Classic 30 Output Transformer Specs ^hot^ Info

These are known to fit the Classic 30 chassis footprint and lead length:

8,000 ohms (8kΩ) center-tapped

Turns ratio is the heartbeat of the transformer. You can verify a healthy OT using a variac or a signal generator. peavey classic 30 output transformer specs

In this 2,500-word deep dive, we will unpack every electrical, physical, and performance spec of the stock Peavey Classic 30 output transformer (OT), including winding ratios, impedance, DC resistance, core size, mounting, and aftermarket alternatives. These are known to fit the Classic 30

While Peavey's official documentation focuses on the end-user experience, technical specifications for the stock and replacement OTs reveal its underlying design: : 30 Watts RMS at clipping. Operating Class : Designed for Class AB push-pull operation. Output Taps : Features both 8-ohm and 16-ohm secondaries. Internal Speaker : Typically connected to the 16-ohm tap . Internal Speaker : Typically connected to the 16-ohm tap

| Lead Function | Wire Color | Notes | |---------------|------------|-------| | Plate (V5 – EL84 pin 7) | | Connects to pin 7 of output tube socket V5 | | Plate (V6 – EL84 pin 7) | Brown | Connects to pin 7 of output tube socket V6 | | Center Tap (B+) | Red | Connects to B+ supply (usually +360V to +380V) | | 16Ω Secondary (to speaker jack tip) | Green | Main output for internal speaker | | 8Ω Secondary (unused) | Yellow | Often taped off inside chassis | | Common (Ground) | Black | Connects to speaker jack sleeve/chassis ground |

Critical note: Do not confuse this. The stock transformer is a universal 4/8/16 multi-tap like a Marshall. It is a dual-secondary transformer: two separate windings (16V and 8V equivalent).
