Mahavishnu Orchestra - You Know You know

I am Sorry I never saw this thread. Yes, I am retired and living in Spokane,Wa. I do still work on interesting and vintage amplifiers from time to time. I do a far amount of work for a local backline company as well. I have not done a Longhorn Bassman mod in quite a while. I did do the mod to both t...

The best glue for tweed or tolex is Hide Glue. You should have no trouble finding it.

There are a lot of misconceptions about what makes a good or great Harp amp. Yes, it should have a low or Olden times normal gain front end. The biggest factor to getting the Overdriven Harp tone is the Microphone ! and how it's cupped or sealed. Which overdrives the Element. This is why Bullet mics...

I built a clone of the 5e7 bandmaster and used ALL Carbon Comp resistors just like the original 57 I cloned. There is no noise to speak of and it sounds awesome. Not bashing metal films or carbon films, just want to point out the noise is not an issue at all. Better to pay attention to lead dress an...

I am well, Enjoying retirement. But I still seem to be working on amps! But only vintage ones now ;-). Been gigging more too ! Just rebuilt and modded an old HH Scott hifi tube integrated, 233. Came out really good. Now that was fun. Gigged with my old Gibson 79RVT last night. The Tremolo is almost ...

Lazy Lester, all

They look like 100k to me. He did increase the coupling cap to the phase invertor.

What about a bucking transformer. Solve all your high voltage issues.

I would happily meet up with you.
I promise to be good.

I apologize again. Now I am embarrassed even. Woke up on the wrong side of the bed. I should not second guess your decision. Farty sounding. I would have first tested the tubes, even substituted and biased first. Crappy speakers can get farty. Too large of a coupling cap can be farty. As a tech who ...

I apologize. I was feeling cranky.

I did not see your post . I retired last year and have not been too active on this forum. I do have a few refinements . The lead dress is critical especially on the normal channel after the mod. Definitely use a 500pf coupling cap to the phase invertor. I prefer polystyrene but use what you got. I'l...

Congratulations on your recone.
Kapton, nomex and paper all sound a bit different.
I usually prefer paper even though the ability to dissipate heat is the lowest of the three.

It really bothers me that this passes for amp tech work.
No diagnosis, no testing, waste of time and money.
I am glad I retired , too many wanna be techs .
And please tune your guitar.
