The Amp Garage

Aby one knows what type of OT is in JM Amp. Just thinking about build a 50w version. Thanks.

And one more. After looking closely at picture l see that on V2, where all schematic's show 68k resistor on the picture looks like 6.8k blue, grey and red, not orange. It's clear colour red. Any one can confirm that.?

is the PI have 220k and 91k resistor or that 120k and 91k and on the top 2x 100K on the other side ?

Does anyone knows what make is this resistor, It has small holes in the end leg of the resistor. I think the carbon film resistors 0.5w. What amplifier there been used in? Thanks to anyone.

Hi, When i'm in OD channel there is no effect on Master, Level knob is effecting volume and Drive don't effect amount of overdrive as it should, it's getting crazy loud and little bit dirty, but is too much to play at that volume even with OD trim half way up. Thanks

OD db at this this settings is about 120 db. and that is very loud and no drives just a big almost clean sound.

Thanks for reply i'm try do what you asked me for. I make a photograph to show you my settings and the OD trim is at noon and there is no sign of overdrive and clean channel has the same volume as overdrive channel and there is no sound of overdrive just a big big open clean tom almost because level...

ok I measure db and with Master at full and stop volume at 2.5 and that give me 100db.

If l turn Master full up and volume to about 8! Ok I will tray explain like this .If l use the Amp by it self, no clator wich is another volume controller then Amp is very loud in OD with PAB and midboost on. Volume at 5, drive at 6 and level at 2, and very little of overdrive coming up from Amp wit...

Hi Phil my problem with overdrive has been solved and at this moment i have a problem with the clean channel to not be so loud as much as overdrive channel. It's much too quiet comparing two overdrive channel which is very loud as you expected from 100 watt Amp. Other than that amplifier sounds fant...

Ok l add some photos. If you can find something unusual please let me know. thanks and happy new year guys.

I was start to worrying that i've done something wrong again with wiring. My amp is not bluesmaster is just standard hrm so wiring will be the same as bluesmaster. Would you have any idea what could be wrong with my clean channel having low volume or lower volume comparing to overdrive channel. Than...

By the way my amplifier is HRM not 183. Thanks

Are you trying to tell me when i'm looking on an amp at front and master volume it's on the right close to presents control that pot should work with overdrive channel or is only for clean channel. thanks guys
