The discrete TC-7520(SE)(+) line output

Thanks for that Andy. I'll look into that.

By the way, the first batch of the Gator are now being sent out based on my list. The next batch will be with me at the end of the month.

Stanley, is payment for Gator +freight still via Paypal?

Yes it is. you'll receive a PM in due course when your name comes up :). The first batch was very small, and not everyone who showed interest are a member on AoS so their names are not on the forum list.

Someone mentioned to me that this PCB could end up as a collector's item, and be traded at a higher price than what it was bought for..

"collector's item" aye... it might be a better investment than the stock market:violin:
well I think that I will make do with one for now

A standard audio PCB was recently listed by someone for £35 plus P&P. Surely the Gator is worth more than that ;).

Hi Stan,

Was just looking at your website (which I think you've updated recently?) And spotted a typo and a broken link..

From http://www.homehifi.co.uk/main/main.html

"Music dowloads"

and "Spectrum Mix2" doesn't go anywhere ATM..

Guessing I'm on the 2nd list then :( Still looking forward to it tho :)

Cheers Kendal. I'll take it up with The Merchant Brothers. Their link must have expired on that freebie.

got my Gator this morning, thanks Stan, quality service as per usual... difficult to determin improvment or otherwise in sound at the moment as my upstairs system has changed a lot recently ... seems to be louder than the passive mod ... i assume that is right? or am i going mad?

i assume by the fact that i have sound comeing out its all in the right way round?

Hi Hamish, as I mentioned in the 2nd line that starts this thread off:
I wanted to find a solution for the low output of the passive mod and preserve the headphone output capability, but didn't want to go overboard with a complex discrete opamp type design. The gain required is only between 2X to 4X so a single ended class A design with just 10% negative feedback was all I felt that was necessary. No need to crack a nut with a sledge hammer .
So yes, the output is higher than the passive mod by about 3dB. And yes, you have plugged it the right way round.
Compare the Gator versus the original audio board in order to get an idea of how much an improvement the Gator is. Output level should be the same on the fixed output, but higher on the variable output.
Then compare the Gator versus the passive mod. Sound quality should be about the same, but the gain of the Gator will be higher. The dynamic range should also be greater with the Gator, and the bass speed should be better than the standard audio board.

Received, installed, works! Doesn't sound like it will need as much burn in-time as the passive cap mods I've tried - sounds great out of the box - but too early to make any proper comments or conclusion.
