Hi KLe,

Nice work.

No problems? Plenty of power?

Burned in yet - how about some listening impressions?

Cheers,
Greg

My GB300 kits arrived today. The PCB's look to be nicely done and I look forward to assembling them. I'll post pics in the Lab circle. BTW Greg, the post card was a nice touch.

Sound good.
I too am waiting for a few to arrive, and we will get them finished up and have a listen .

Looking forward to them.

Hi Mike - that's really quick delivery. Better than the poor guy in NY who waited a month, no show. So I sent him another and the first turned up the next day!!

Al, yours should be just around the corner. I want to find out how they sound with those new 95db towers of yours - I might be up for a pair!

Liven up the neighbours.

Cheers,
Greg

Thanks
Yes going to have the amps finished and going with them new towers is the idea.

Hi Greg
The GB300D amp keeps getting better and better, as, they run in. I will be posting a review over the weekend.

Get used to it Greg, I send and recieve stuff from the US all the time and it can take 3 months if something is held in their customs.

It is quite different from sending to/from the UK, where it will only be a week or 2 at most.

mgalusha,
Please post here when you begin posting in the Lab - that way we'll know when it happens if we have "Notify me" set.
Thanks

I'll be sure to do that Jerry. I did take some photos of the bare boards and kits yesterday and with any luck I'll start putting them together tomorrow night or Saturday.

I've started a thread in the lab circle for a build of the kits. It would be nice if other AC members building these offered their thoughts and experiences as their amps come together.

Hi All
A friend listened to my GB300D based system, on Wednesday (< 12 hours of run in), and I asked him to write for me summary of his listening experience. This was his experience ...

Quote

I'd be happy to summarize my listening experience at your home this past Wednesday.

A brief recap.

The system in general performed at a very high level, and seemed to get sweeter and smoother as the afternoon wore on. What I heard was a very relaxed, effortless, and lifelike musical presentation. It was engaging and thoroughly enjoyable. The stage was wide and deep, and retrieval and resolution of micro detail was excellent. Most important to me, was the obvious coherence. Time related linearity bettered some of the obscenely expensive systems I have heard.

The interconnects were a major component in the chain. Changing them out made a huge difference, which also attests to the ability of the loudspeakers to reveal these subtle--or not so subtle shadings.

Hope this proves helpful.
Randall

Hi All
I have built Greg's GB300D, his 300W amp modules. I am running them at 200W/8ohms, 400W/4ohms (+/-63VDC rails).

I asked Greg for some tweaks and he suggested the following

Quote

R) important Resistor's for substitution are R4 (1W is good) , R14, R3, R2.
C) important Capacitor's are C19, C3, and C1 if you choose to fit a DC blocking capacitor.

Hope this is helpful and all tweaks (that work) are welcome

Newbie here!

I'm considering the GB150D not as a kit but fully assembled and tested. If I were to buy this amp, what other parts and installations would be needed to have a fully functioning amp

I did, for awhile, ponder the full kit but it has been years since I've attempted this type of project ,however, I'm not completely ignorant since I did construct a Hafler amp/preamp about 15 years ago without much knowledge of electronic theory; just connected the dots.

Has everyone who ordered simple Killer amps received his kits? Amplifierguru doesn't even reply to my many PMs.

It's been almost a month since I paid via PAYPAL.

amplifierguru · « **Reply #97 on:** 1 Mar 2006, 05:57 am »

Hi TNT,

Funny, I check the PMs 3 times a day - your two just appeared and I answered.

You should have your kits this week. They were despatched last Sunday, your time. That'll be < 3 weeks from order, if there are no inordinate delays in the post.

I know you are anxious to build them.

Cheers,
Greg

James Romeyn · « **Reply #98 on:** 1 Mar 2006, 02:48 pm »

Funny how two perspectives of the same incident can be so different.

To the buyer "3 weeks" is "almost a month".

The the seller 3 weeks is just over 2 weeks.

TNT · « **Reply #99 on:** 1 Mar 2006, 03:54 pm »

The only reason I was anxious is Paypal gives you a month to ask for refund.
now I can look forward to receiving it instead of wondering. All is well...
