Does removing the screan from a k55m driver make it louder?

I got that same 150 watt amp, pre, tuner, and meters at a thrift shop for 325 dollars (great thrift find) had the amp in for repair 3 times. Thought it sounded great/awsome my first real power, till i got my mcintosh mc7270 and my adcom gfa585le then i knew, played with it for 2 or 3 years then sold the mitsubishi and all its components for 300 dollars via craigslist

I that amp and all its components, tuner, preamp and meter I picked it up at a thrift shop thats right thrift shop for 325.00 dollars it was a tank (great) sold it year ago 300 dollars I replaced it with a mcintosh mc7270 (270 wpc) replaced my mc7270 with adcom gfa585le (250 wpc)

For what its worth my adcom 585le hooked up to my cornscalas sound better than my mint mcintosh mc-7270! So......

Can the K53ti be crossed at 600hz with a k601 horn?

I know this is gonna sound green but which kinda caps i order, polar, aluminum, bipolar, radial 105 or 85 degres 10ml x20ml +/- ?

Are the potentual leaking caps on the input board? did you replace the bypass caps on the power supply and/or on the input board?

Three sides it is my freind thank you

That is wrong cornwall "2" does not use damping material and damping material does very little on a seal cab and your not suposed to "stuff" the cabinet with the material your suposed to "line" the walls. thank you kenneth

How do you safely discharge a PS cap? i registered with diyaudio and couldnt find any pics on how to discharge. thanks ken

Heres a model 325x can be had for under 150 i prefer the 525x there both really easy to use make sure you get the mic with it.

ADC Sound Shaper Automatic Computerized Equalizer/Analyzer model ss-525x has remote and microphone for room leveling BSR makes one also, ebay for around 200 dollars and new caps inyour speakers, unless you want to spend tons on equipment to get it right

Klipsch doe not use damping material in the cornwall ll and I dont know why. Any how I purchased 1 inch wedge foambymail (remnants) enough to do the whole of each cabinet or should I just do 3 sides (top, 1 side, back)? My second question, they say this will improve the bass responce but why does it improve the midrange?

Power supply caps are those on the output pcb assembly? I think it shows 47uf/160v capacitors electrolytic, I downloaded the schmatic and did not see the power supply board. thanks ken

Yes compared to my mc7270 bass is more controled yet still deep especially with my cornscala's with no damping material inside the cab resonances were out of control with the mc7270 probably due to its low damp factor (30) not sure that i need damping material now also the 585 seems to have more detail the mc7270 seemed rolled off but was smoother sounding. Yes the power supply caps ill look into. no i dont have experience but ive built xovers and very mechanically inclined so maybe, i wont do it unless im sure i can. Is black gate good? I will be using it with McIntosh MX-130, Sound Shaper ss-525x, Cornwall ll mod to Cornscala, PH800/K55M and ALK AP12-500 ES-5800

Hello I just bought a very clean GFA585LE with no signs of leaking caps and was wanting to change them before they do and upgrade to better components theres a company that offers this service but I was looking to save and do some of it myself it myself. Here is what they offer, Install high quality audio grade capacitors and low noise metal film resistors in working driver, output stage, and power supply circuits for greater musical clarity. Areas targeted for improvement include the input circuitry, feedback loop, output stage biasing, driver/output stage/power supply bypassing, EMI protection. They also state they use Rubicon black gate capacitors, I searched on ebay for these and couldnt find them, is there something as good I can use and what would be the values?Check DC offset, check and adjust bias, before/after modification extended listening tests.

Hello i just went through your site and read some post about the m1.0t and i like what i see in the mkll but i have to sell my mc7270 first. If you know anybody it has the wood case in beautiful condition as with the amp is also 1500.00 OBO. Thanks Ken

@ emmette Hello, I currently run mcintosh mc7270 and mcintosh mx130 2 chanal set up but have to sell mc7270 to get my contractors license and thought i would replace it later but for now use something another forum member carver m1 is one of the only carver he recomends how much for your m1? kenneyh

Hello has the gfa-555 ll arlready factory updated and bypassed is it a mosfet design how about the gfa5500 theres a gfa5500 pristine for 395.00 i have a mcintosh mc7270 with walnut case in beautiful condition for sale because i want to get my contractors license and needthe money so i was loking for a less expensive amp to use for now and then buy another mac lter thanks ken

Is Adcom GFA-555 Mk ll a good match for Cornwall ll or Yamaha M80 or Carver 200 watt+ amp? Looking to buy.

Is Adcom GFA-555 Mk ll a good match for Cornwall ll or Yamaha M80 or Carver 200 watt+ amp?

Has anyone tried this mod specificaly the port mod?

Been bussy and still interested in your recomendations I saw a thread in audio asylum march 2002 "old mcintosh" that leads me to believe you know what your talking about, I'll get back to you soon. Thanks Ken
