Initially not working;
DBT stayed on bright. Some electrolytics in the power supply v.bad (DMM & $25 component tester). Changed PS 'lytics, slightly higher voltages. DBT dimmed down "ok". Retested, bounce not noted! Changed ALL 'lytics.
Tested with cheap 3-way speakers, & the bass/woofers "bounce", no input, both speaker outputs switched & unswitched, headphones not affected (speakers disconnected) apart from background humm.
If the Bass Control is minimised/defeated, the bounce goes away. Bounce affected by either Bass &/or Volume controls.
Sound with a CD source, sounds ok, but with higher volume the woofer visually bounces.
Should I check the MKT type caps, re the bass & or speaker controls? Or is it something else?!
