Hi guys,

I am in Durbanville and got a Marshall TSL602 thats in need of a repair. From what I could figure out its needs a valve and fuse replacement.

The repair I would realy like to do myself, but I don't know where in the area I can get hold of the fuses (Mains Fuse TI6AC - 230V and H.T. Fuse T500mAL) and valves (12ax7 and EL34) needed. Do guys know of a shop or someone in the Durbanville/Cape Town area where I can get these items?

Also if I am to finally give up on the project where can I find someone to repair my amp at a reasonable price?

Thanks in advance guys
    Fuses you can more than likely get from Yebo Electronics in Boston, just take a sample with, thats where I got for my Classic 30. Tube wise, nowhere unfortunately. Graeme (who repairs amps etc) does a monthly or so order from TubeDepot otherwise your only other bet is MrValve in Jhb.

      Thanks for the info Nick, a big help, luckily Boston is closeby! I was thinking of even ordering the valves via Take2

      Thats the prices with shipping included. If that fails, I will make contact with Graeme.
        Question is why did that fuse blow? Fuses blow if something is wrong with the electronics. Now it could be that the valve or its socket caused the blow out...so rather get it checked out first ....My 2 c

          Wel its only the HT fuse that blew, and to quote from the manual:
          "This fuse protects your amp in the case of a fault occurring with any of the high voltage circuitry. The usual reason for this to blow is when an output valve has become faulty."

          The Mains fuse is still fine, I just want to stock up on parts while I am at it. Hopefully a complete valve swap will resolve the issue why the HT fuse blew in the first place. ???
            Fuses blow when the Power amp section goes.... so bad set of tubes could be the answer, or a bad rectifier tube....

            I only know this as one of my el84s tripped out taking the rectifier and fuse
              Take out the power valves, fit a new fuse and turn on. If the fuse lasts a minute or two without blowing, power down and fit the replacements. If the fuse blows without the valves in, take it to Graeme or Karel Mars for repair before fitting the new valves.

              I dunno - shops used to stock valves, but last time I was in Bothner's they said that their repair guy kept them all in the workshop these days, which is ridiculous - most valves are easily replaced (except power valves in some adjustable-bias amps) and they are actually something that you should carry spares of to gigs.

                Thanks Alan, I will try that, wouldn't do me much good if I refit all the valves and the fuse still goes. I checked the valves last night for cracks, but couldn't find any.

                Yeah I was at Bothners last week and I got the same answer, and they mostly just had EHX, Marshall and Solvtek valves on their list. I would like to try out JJ Tesla as I only heard good things about them.
                  Matt Allison (Matta on this forum) used to carry them, but he's been quiet lately. Definitely Mr Valve in JHB will have JJs.
                    Ok, so I just ordered my valves via take2. 4x T-12AX7-S-JJ and 1x T-EL34-JJ-MPB, paid R1075 for them, hopefully they will get here in one piece ?
