8,000 ohms (8kΩ) center-tapped
The Classic 30 chassis is mounted upside down inside the cabinet, with the tubes pointing down. The heat from the four EL84s rises directly onto the circuit board and the output transformer. Over decades of use, the insulation on the internal windings of the OT can become brittle. peavey classic 30 output transformer specs
The primary winding features an operational center tap (Push-Pull configuration) designed to look back at a quad of EL84 power tubes running in parallel-pairs. Approximately 4,000 Ohms ( Ωcap omega ) . 8,000 ohms (8kΩ) center-tapped The Classic 30 chassis
The reveal a functional but budget-conscious design: an 8kΩ primary, 16/8Ω secondary, moderate DCR, and a modest core that saturates pleasingly at high volume. If your stock OT is working, you have an authentic “grunge-era” workhorse tone. The primary winding features an operational center tap
