Anybody have any clues on how to get MORE bass response out of this amp? It sounds great but I really need more bass response. I realise you can only get so much bass out of 10's, but it does sound a little mid range oriented. New tubes, speakers, biased right on 14mA(they'll eat themselves much higher-I know), just still could use some bass added. Mike Kaus | ||

You might experiment with changing the series coupling caps on the first two input op-amp stages (C1 & C6) from .1uF to a larger value (start with 1uF and go up in value to increase the amount of low frequency energy in your signal until you get what you want). You could also increase the value of C7 to a 1uF or 2.2uF or lower the value of R8 to 10K. This should also increase the low frequency content of your signal. However, I would try the coupling caps first before messing with the feedback loop filter. Steve | ||

Thanks Steve, I'll try that first. Love the 65 since my main amp was a JBL Twin! This I can carry. Re-capped it, Weber Ca10's and a fan put in the back to cool the new JJ's and it should last ANOTHER 20 yrs or so. Mike. | ||

There's an itch toward a Twin, but maybe I can change some components with my MM210-65 w/PI and make it sound close to it. Its been recapped by Terry and have the Mullards in. Speakers are stock. I think some people have called this thier "mini-twin". I say components and not have to deal with soldering so it can be brought back to stock. Or as stock it sounds like a twin?? hubert |
