Lovely amp designed for Blues Harp (Harmonica) making strange crackling noises…Nice 2×8″ Jensen SpeakersPine cabinetTubes out for testing (except rectifier tube)All tubes tested good but still crackling preamp around the middle preamp tube..Turned out to be a 250pF silver mica capaictor that was defective. Here it is cut out and the noise disappeared. I replaced with a new cap and she was singing sweetly again!Original 2×8 Ceramic Jensen custom designed speakersReplacement Weber Alnico 8″ and 10″speakersDust cover from magnetHuge alnico magnets in the Weber Replacements!Trial position of chassis, magnet too close to output tubes.. dropping the smaller speakers improves mattersOld baffle out¬New black cut and size checkedHoles cut!Blackboard paint drying…Drilling holes for the screws Grill cloth back onBaffle back in the cabSpeakers fittedNeeds chassis nowChassis inWill the tubes fit?yepnot bad!Some space before the magnets!Preamp tubes have clearance!With an old pair of PM 6L6 tubes no hum and sounding sweet… great speakers!New tubes… big bottles!Plug socket added to help store the lead safelyLeonid’s pedal board. Some great sounds to be had!Rechargeable battery for the pedal board.. neat idea! Nice Dutch Blues Harp (Harmonica) amplifier which was crackling due to a dodgy capacitor… She got a full service and was singing sweetly again. Based on a tweed bassman she sounds great! She then came back in later to undergo a speaker revamp from a 2×8 Ceramic Jensens to a 1×8″ and 1×10″ Weber Alnico speakers… Made her sound even sweater IMHO.. TOugh job squeezing them in!
