Hello Bob , this is Mike who bought a couple of your daughter boards last year and picked them up from your place . The amps I repaired with them are still going strong .However my original Vox mini 3 which was always working has just failed while I was tapping quite loudly a microphone plugged into the appropriate socket ( it was continually cutting out before the final demise ) . Do you have any more of your product ? , also I have lost the emails with your contact details . Could you help at all ? hope you are keeping well , Mike . { mic }
