MARK III PREAMP TUBE TESTING

Guys Need help checking preamp tubes on Mark III , Should I try this test on V1 using a pencil hitting the tube gently, and should V1 be dead silent when tapping the tube being tested using clean Channel on max volume? Or I ll hear the tapping in the speaker? Any other suggestions to perform this te...

Re: Listen , How close is my Mark III to the IIc++?

Sounds like a III to me, mushy low end transients (not inherently bad but not like a IIC_+), what were your settings? This captures a IIC+ perfectly to me, although I can't tell if his treble shift is pulled. My III+ sounds much closer to this with it not pulled but "the" IIC+ sound always has it p...

Re: Listen , How close is my Mark III to the IIc++?

Well , The Settings are a bit weird as the mod i have made is a bit different , it includes connecting v2 with v3 directly , and this cancelled my clean channel , i will post the whole mod after i am totally done. the treble pull shift is off , as when i pull it out , it feels more like iii than iic+.

Re: Mark III Treble Pull Shift?

12AT7 will make the amp another beast , it will tame some harshness without affecting its aggression, will give it a bold 3D character with more bottom dynamics. I have tried many 12AT7 tubes like JJ Gold pins, Genalex gold lion gold pins , but the best was the tungsol 12AT7 in the PI.

Re: Mesa Mark III NOISE , Is it cap filters problem?

Is the guitar's volume set to zero or minimum? Do you have florescent or CLF lamps in the room or the same circuit as the amp? Does it make that noise in other rooms or when plugged into a different circuit? Do other amps do this in this location? It sounds like the guitar is picking up outside int...

Re: Mark III Treble Pull Shift?

Yes I am with you in this opinion , when it is not pulled it is better , more full tone like the IIC+ , I am using a pair of tungsol 5881 in power tube section and 4 tungsol 12AX7 Gold pins from v1 to v4 and the PI I use tungsol 12AT7. Sounds pretty great with this setup

Re: Mesa Mark III NOISE , Is it cap filters problem?

Simply the guitar is plugged into the amp directly with no effects in the loop.
Pickups are seymour Duncan distortions.
