    Boss TU-2 Tuner lagging upon hitting footswitch

    My tu2 boss tuner has about a 5 second pause before it can start tuning. Doesnt matter how the pedal is powered, it always has this brief lag before it senses a note. Only upon hitting the footswitch from off to on. What part do you think can be causing this? I will add a schematic..can it be a power supply or footswitch issue?

      Samsung PN51F8500AFXZA broke off the tuner's F connector, can't get tuner de-soldered
      by DXseekerMO
      I can hear Fred Sanford now...."YOU BIG DUMMY".....I pulled the "F" connector out of the tuner by accident. The tuner number is BN40-00248B. Low and behold I had a scrap board with tuner number BN40-00248A. Although the tuner is different (according to Encompass.com) it's footprint on the board is exactly the same as the 248B so I decided to de-solder the tuner off the scrap board to see what I was getting in to.

      As you can see in the picture the terminals and solder pads are super small. No matter what I tried I could not get either the terminals or support...

      Does Changing Out Caps In A Tuner Effect FM Reception
      by Mark R
      "TQ" Subject at hand is a Marantz 120 tuner. The tuner lit up but no output. Recapped the entire unit. Before it was working fine tuning in Stereo and Mono. Now it just about tunes Stereo and some of the mono stations are weak. Nothing else was changed. When you do hit a stereo station the stereo lamp will come on but flickers as it's trying to hold the MPX signal.

      I don't see how bringing the unit back with new caps checked by my Sencore LC103 would effect the FM section. Every Value is as it was from the factory?

      Any Thoughts?

      55PFL4908K/12 DVB-S tuner not available
      by Ierwin
      Hello everyone,

      I have a rather strange problem with this Philips I just repaired.
      The set came with startup problems, I checked the PSU, found some puffed caps, replaced them and now it is starting perfectly.

      According to the philips website this tv should be equipped with a tripple tuner.
      However there is no option to scan for satellite channels in the menu.
      It only shows the option to search for DVB-T or DVB-C channels.
      The set is equiped with the F-type connector in the back so to me it looks like it is indeed equipped with a Sat tuner....

      Marantz Model 120 Tuner Craziness I am Stumped!
      by Mark R
      My Marantz 120 Tuner stopped receiving Stereo signals. It works fine other then Stereo. I have a fully loaded shop here with all test equipment except and RF signal Generator.

      I get great reception on FM so I have used that signal troubleshoot. I have been all over the MPX board and replaced all caps. Also the entire power supply caps were replaced.

      All Voltages on the MPX board are good... all Transistors Good...All Diodes Good and other components.

      The stereo lamp is good as I powered it up and it lights. The signal flow to that lamp is unbelievably...
