| Where are you today? I've been enjoying the liquid mid-range/3D imaging/transparency/realism of a tubed top-end(Cary SLM100's, modded) and the speed/definition/extension/power of a MOS-FET bottom-end for the past 19yrs(was a Hafler DH-500, now a TransNova 9505, both m... | |
| Reliable Sources for 6SN7 Tubes While you are shopping for 6SN7's: Don't miss the Sylvania CHS, VT-231, bottom getter tube from the 40's. It's extension(without grain), transparency, liquid mid-range, slam and imaging are far better than anything manufactured today. They look li... | |
| What capacitor values? I'm not certain of the response of your midrange, never having seen the data. BUT- Most don't operate smoothly up to 7500Hz. If you look at this response: (http://www.madisound.com/catalog/PDF/scanspeak/12m_4631g00e.pdf) You'll note how erratic th... | |
| Tubes? +1 for Mr A's advice. Further- The majority of musical instrument amp repairmen own tube testers, as tubes are widely used in music/sound gear. Check your yellow pages, and make a couple calls. | |
| What capacitor values? Mr H- No risk at all. It would bring the mid in at about 1kHz which is probably closer to the the neighborhood of the 12's natural roll-off. See if you can find the data on your 12". Often that will supply you with a freq response plot. Check it's... | |
| What capacitor values? If you like the sound: Leave it as is! You've no one to please but yourself. Based on the impedances you gave, the values/points/slopes should be as noted. I was suggesting what generally works well for x-over points. Especially with a 12"/5 1/4"/... | |
| What capacitor values? Well- That would bring your tweeter in a little above 10kHz, and your mid- right about 4kHz. The mid isn't doing much midding that way. I'd say 80uF on the mid(500Hz) and about 5.5uF on the tweeter(about 5kHz). I suppose if you were to go with an ... | |
| Lack of depth problem Speaking of bass: depending on where those subwoofers are in relation to the mains- a time shift can screw up your sound stage also. There's a lot a ambience info in the bottom octaves. Try moving them into alignment with the mains as an experiment. | |
| What capacitor values? If those speakers are 8ohm: the 200uF cap will cross at 100Hz and the 1.76uF over 10kHz. If they are 4ohm drivers: 200uF= 200Hz, and 1.766uF=somewhere over the rainbow, I mean- over 20kHz. I seriously doubt the mid-range actually has the ability t... | |
| Lack of depth problem Better make those "your" ears! | |
| Tact Audio Great Service Here is one of the threads that I responded to over two years ago(way before Mr G's issues/rants surfaced): (http://forum.audiogon.com/cgi-bin/fr.pl?aamps&1166278482&read&keyw&zztact) You'll notice that I mentioned their service as... | |
| Lack of depth problem Hello Vett93: I've used the VT-231(IF it's the bottom getter tube from the 40's), and it is an excellent tube with regard to clarity, imaging, dynamics, etc. Actually I'm saving them for back-ups now. I did find more depth of stage with the Sylvan... | |
| What capacitor values? If the sound has been excellent with the existing values, why would you change them? Keep in mind- When the new caps are installed, it will take a number of hours(perhaps 200+) for them to sound right. | |
| Tact Audio Great Service My response is hardly a plant! I've been very pleased with my Tact over the years, and have mentioned that in here several times. If you want the facts, follow what actually happened here: (http://tech.groups.yahoo.com/group/TacTAudioUsersGroup/me... | |
| Lack of depth problem Vett93- You mention having your Counterpoint "voiced". Was it converted to 6SN7 drivers? If not: what 6922 type drivers do you have in it? Do you know anyone that would loan you a tubed amplifier for an audition? |
