Hornby Class 56

I know that this is perhaps a shade to new for Parkstone's time scale, but after seeing them in Cardiff years ago i have always had a soft spot for them. 

I bought a Hornby Class 56 sometime ago. Sound fitted all singing all dancing, admittedly it was second hand but it seemed fine. After about 3 months the lights failed. After taking the body off, i thought it may be the age old problem of the contacts on the cab floor. All good their. 

 

After investigating further it would appear to be the PCB is dead, nothing, ziltch, zero, caput.    

 After speaking to Hornby they can't supply a new PCB. Infact it's not even listed as a part. I have tried various other part supplyer's but to know avail.
There does seem to be about 3 maybe 4 different light systems

Not really wanting to go down the road of fitting a kit from Express Models just yet. Perhaps someone out there may have one as a spare.

 It seems odd that both ends went pretty much at the same time
