    Default My tube amplifier adventure

    I had never done more than sticking a sheet of ERS under the lead of a player, one day decided to change that and started with this Chinese amplifier...

    I will include the link to my page instead of repeating it here, this way it stays up to date...

    Very nice indeed Antonio, looks very neat and tidy. Was it semi assembled or a bag of bits?

    It was assembled, but I removed as much as I could, or thought I could...

    Then replaced the tubes, of course, most capacitors, plus the resistors on the input stage, it was fun, and useful to learn how to fix it, as it is a problem for me to get someone to fix it here in Latvia...

    Nice mods Antonio. I see that you used some massive wiring in there. Maybe you should use the same type of wire for the output connections to the loudspeaker terminals?

    I used what I had arround...

    While it lasted, I used "thick" silver wire Zanash sent with some bits I bought from him, then I used wire from speaker cable leftovers, single strand silvered copper with thin white isolation...

    My soldering technique is very basic, so I try not to touch what I am not modifying...
