# Hurry Home Early

## Recommended Posts

for my own personal concert ….

heres my little home experience

sony e9000es

bsr eq for the spectrum analyzer

flac streamed from bluray

2 m1.5ts one purple one blue both matched internals

a760x for the lows powering 12 and 15 sony mobile es subs in custom built boxes

vmps super tower iia/r

vmps qs808 for rear

hoping to get another set of vmps towers in the future for the rear and then my life will be complete

vid of the a760 after I recapped it doing its thing lol

I actually got quite few carver pieces.

m500t m1.0t 3 m1.5ts a760x a753x a500x a220 2 tfm-15cbs tfm-35x tfm-55x tfm-24 tfm-45 and just scored a c-1 preamp which showed today yay.

heres a pic of a tfm15 and a220 I just recently listed for sale

ill add more pics when im alittle more organized and my final build is setup

and yes that is red white and blue like an American amp should be haha

WELCOME to the forum @allflehisequalwhenburnt!

I see you've got quite the collection of carver gear...

thanks, I do alright most mods are fairly easy and I spent most of my childhood soldering team associated rc cars lol so soldering is fun to me.

still learning a bit but so far brought 3 amps back from the dead so cant complain I suppose

honestly the m1.5t is my favorite. it has the sweetest sound of all the solid state carvers to me. the m1.5t is very controlled and very precise. has no problem powering those 16 drivers at 6ohm. everyone always goes to the m500t for best sounding but I disagree. and every 500t ive seen in action had no control over the woofers at all. just kinda floated around. ive heard 4 of em all the same. however I do have m500t that ill prolly mk2 at some point and recompare it. maybe its a better amp for mids and highs alone idk

however I don't run my system without subs and hands down any A series 2 channel amp is the best amp for subs.

ive tried all other carver models and the a220 would over power m series and most of all tfm series. unfortunately I sold the silver seven t's and tfm-75 before I got my hands on an a760x to compare. the lightstar only amp haven't gotten my hands on yet

a760x so far haven't found something to compete with it in subwoofers at 4 ohms. so....

that's why I bought a m1.0t recently time for an mk2 opt2 upgrade and give the a760x a rival. however I don't think the m1.0t will win either. but im also looking for most power out of one cord.

but hey nothing wrong with experimenting having fun. what I like and what everyone likes and opinions will differ. but always keep an open mind

Nice set of equipment!  OCCD is strong with this one!

Glad you found us!  Looking forward to seeing more photos!  Welcome to the Carversite!  I think you will fit in well here!  As always enjoy the music!

I've been a fan of VMPS speakers since the eighties. A close friend had a pair of Super Tower IIs biamped with 4 M400ts. After he sold the cubes, he biamped with a pair of Adcom amps.

One day I went to his house, and I had to wait until between Ozzy tracks to ring the bell. When his wife answered the door to let me in, we went into the living room so she could turn down the stereo, and we found their ceiling fan in the floor.

I loved those speakers, and he sold them for close to nothing. He didn't know they could be repaired, refurbed.  Once Brian Cheney passed, he thought they became boat anchors.  I wish I would have known.

There's three pair of Super Tower IIIs on ebay now.

I tend to lean in this direction as well, but do like the m500t (see next comment).

The m500t is my preference for lower listening levels, preferred over  the m1.5t.  It seems to provide more definition and soundstage without needing the volume at 11.

A very belated welcome @allflehisequalwhenburnt - you have a great set-up (or should I say set-ups, as it seems to be a mix and match, based on the OCCD acquisition of the day?).   Like others, I thought I knew what the addictive qualities of OCCD meant, but compared to you, I'm definitely not worthy.  All I can say is:

Replace R404 and R405 with LDO regulators. Cost = $5-6 including heat sinks, added effort is minimal.

I needed a few parts from Mouser, and I have one more C-1 at home that I want to do at some point, so I just added the regulators and heat sinks to my order. Arrives next Monday. I have posted a few pics in the past, but when I get the parts, I plan to write it up with pics. Probably get to it some night next week. It's easiest to do it while doing the BillD mod, but can be added at anytime. #### Share this post ##### Link to post ##### Share on other sites On 5/29/2019 at 8:20 AM, jeffs said: The power supply in the C-1 is a poor design. The 12V supplies are unregulated. I don't understand why people go to the effort of doing the BIllD and don't address the +/-12V supply, or even worse, they address it by just lowering the values of R404 and R405. In one case I read a post where the modder purchased an entire range of 1/2W resistors in order to trim the 12V just right. Too much effort. If you use headphones, which introduce the most significant load change, things go out of whack again. Replace R404 and R405 with LDO regulators. Cost =$5-6 including heat sinks, added effort is minimal.

While you can certainly add some regulators, it won’t help with the problem you will have if you change all of the opamps.  The problem will be that the transformer will not be adequate for the new load requirements, it will get really hot, and if left as is I expect it will fail.  When it does, hope that nothing catches fire😮

The transformer is inconsistent from unit to unit so you're right, it's difficult to make changes that will work the same across all units.

I've also had a C-1 that had such a weak transformer that I'm not sure there was enough output for a 12V LDO to even operate properly?

The stock opamps combined maximum operating current is  about 100mA, maximum,  45mA typical. (+/-15V supplies)

Replacing all opamps with OPAx134 would increase this to a maximum of 180mA, 144mA typical.

I believe that anyone who wants to do mods to a C-1 should first look at the voltage levels at the PS rectifiers.  If they are <14V, the transformer in that unit is crap.

For that matter, one can just look at the factory values of R404 and R405, if they are less than 20ohm, the transformer in that unit is crap.  This is not to say that higher levels mean the transformer is great, but the weak transformers are certainly a problem.

just wrapped up my 2nd m1.0t mkll opt2 build. all dialed in and ready to go, cant wait for the test drive tomorrow.

1 m1.0t opt2 on the front  and 1 m1.0t opt2 on the subs

vs

1 m1.0t opt2 on the front and a juiced a760x on the subs.

I still think the a760x will remain supreme for sub duty but I will find out later today

let the destruction commence
