    Jcm 2000 Tsl 60x Serial Loop Mod

    I’m so glad someone finally documented this. Did this mod cause your reverb and time stack to not function?

    Output Transformer Question

    They were spades. I crimped them so that doesn’t happen again. I did run both amps through a different cab as well and there difference in volume there was negligible. Oddly the origin sounded more 3D than the tsl at the same dB on the Meters so it feels louder. I don’t know if this is a...

    Output Transformer Question

    I am an idiot. I got thinking about what was mentioned about mic placement and opened the back of he cab to find one of the positive terminals on the speaker I was moving unhooked. Not only was I micing a dead speaker, I was running in 8 ohms I think. Anyway sound is full again. Still not...

    Output Transformer Question

    Thanks for the relply. The recording setup is an e603 into a sx202 preamp into a ur44 interface into sonar. Same setup for both reference recording. The dB measurement is from a iPhone app so I don’t know how accurate it is but my input meters on my daw show them same level coming in. On...

    Output Transformer Question

    I have a Tsl60 that I like the tone of after some mods. One thing that has always plagued it is that when I record it it sound thin and lower in volume than it does in the room. Recently I’d purchased a origin50 and was recording both of them at the same volume but noticed on the recorded...

    Tsl60 Power Transformer Replacement

    Thanks for taking a look. It makes me a lot more comfortable knowing I've got some more experienced eyes taking a look at my work. This forum is the best!

    Tsl60 Power Transformer Replacement

    So it appears that all is well with this tsl60 power transformer transplant. Here is a link to the probe. https://www.eurotubes.com/store/pc/bias%20probes.htm

    Tsl60 Power Transformer Replacement

    Bias probe from eurotubes arrived yesterday. Worked like a charm. The instructions say that this will read miliamps only so it is only good for biasing however after reading another post on this tool on another forum I can confirm that if you power down the amp and move the leads to the dcv...

    Tsl60 Power Transformer Replacement

    I have not received the Bias probe I ordered yet, but in reading another post from 2011, another forum member was having trouble with his TSL60 blowing fuses. When he measured across w20/w21 (where the B+ plug into the board) he got about 360vac. I'm not blowing fuses an the amp is running...

    Tsl60 Power Transformer Replacement

    I think my bias is set way to cold too. Seems like I read on this forum to set each tube at 37 or so but when using the bias test point on the amp it sees that the mv reading would be BOTH tubes combined. Anyone know for sure?

    Tsl60 Power Transformer Replacement

    Well I didn't die or blow up my amp so that's good. I wasn't able to get an answer from the PT maker or Marshall support on the b+ tap voltage. It reads 330v when I send one of the two wires to ground but when I connect them to the board posts where the dagnall was, the voltage seems to be...

    Tsl60 Power Transformer Replacement

    Thanks, So is just clipping one leg enough to take th out of the circuit or should I remove the resistor all together? It there any benefit to the center tap over the artificial one?

    Tsl60 Power Transformer Replacement

    Ok I see those resistors. So if cut them I should be able to terminate the centerctap at pin w22 since this goes directly to ground? Thanks for your help. Is there any benefit to using the center tap over the artificial one? Will it lower noise?

    Tsl60 Power Transformer Replacement

    So I've got the new PT and was measuring the taps on the existing PT. All have been identified but I have centertaps on he new PT that the stock one didn't have. I've read that I need to remove the 100 ohm false center if Ike going to ground the new center taps. Questions How do I identy the...

    Tsl60 Power Transformer Replacement

    Here is s link to the schematic for the new PT. No 6.3v just a 20v? http://www.mojotone.com/transformers/BRITISH-900-50W-PT.pdf

    Tsl60 Power Transformer Replacement

    The stock one isn't dead yet, I'm replacing it because it vibrates even after tightening. If I measure the resistance at the leads between the sets of wires I should be able to id them I think.

    Tsl60 Power Transformer Replacement

    Here is the Marshall schematic. Can you identify the hv, 6.3, etc leads? Thanks for taking a look. http://www.drtube.com/schematics/marshall/TL60-60-02%20(2003)%20iss7.pdf http://www.drtube.com/schematics/marshall/TL60-60-02%20(2003)%20iss7.pdf
