Markbass TA501 spares or repair £50 Bath

[oldslapper]

Bought this off here recently to see if I could resurrect it. I love the TA501 tube compression and the flexible EQ.

 

The issue is that although it powers up and the fan works, it makes a whining, static and crackle sound, similar to tuning an old radio.  
 

I cleaned contacts, changed the tube and power cable, but the issue remains. It’s likely to be a capacitor issue. I was going to take it to my mate who repairs amps for a living, but realistically I’ll likely never use it since giving up gigging bass.
So yours for £50 collected, plus £10 pp and I’ll include a spare tube.  Comes with power cable and manual.
