I have problem with channel 1 audio crash on play back on beta sp uvw1800.I record with colour bars both levels good ballance on uv meters. But when i play back audio on 1 channel goes too high (crashing) and audio on 2 channel remains good. When i play any old recorded tape audio on both channels show good level. Any idea what can cause this? Previously this machine had been recording good. This happened just recently. Does the head needs to be cleaned or something else. anybody’s help will be appreciated.
