I've been rebuilding a TC 2400 equaliser. In testing I found that it appears to oscillate when overdriven. I have an unmodified 2400 which, when tested, does exactly the same thing
Even with the EQ in bypass the unit will apparently oscillate before it clips. By this point one of the overload LEDs is lit, which should suggest to users to back off a bit, but I wondered if there was design change I should try to stop it oscillating?
The attachment shows a 5 KHz sine wave at the point oscillation starts
