What does it have to do with Eddie Current ?! The amp you're requesting is from Singlepower...

I'd be interested in the single-ended edition.

I can't believe you guys brought this thread back from the dead. I have a pre-production prototype in my hands. I'll post some unboxing photos tonight.

Was that at SF?

Are there any images of the back?  Wondering if it can be powered by an aftermarket 12v PSU and are the inputs SE or balanced or both?  It's running at 12v and how many amps?

Any 12V PSU. 5 amps. inputs SE. EC is redesigning the board to take an external +/- 24V tube PS (which bypasses in the internal charge pump) for a later date. The tube PS is purely speculative at this point.

Gotta love Craig's description of this amp:

 

The Red Top is a portable-sized high-end headphone amplifier so versatile it will run on a 12V battery or car charger! 

 

Most of us struggled with the concept that the Lisa III was supposed to be a 'portable-sized' amp. but I think Craig might be stretching things here. 7" x 10" x 4" high - and all I need is a 12-volt battery or a car to make it 'portable' ? Sweet  ;)

 

 

'Hey buddy - can you give me a jump ? My amp won't start .....'

 

This may well be a great desktop amp in a relatively small form factor, but Craig needs to revisit his approach to marketing copy. I'm sure I'll cop it from the EC faithful. but ask yourselves if any of the above is going to appeal to more than 2% of the people who may be considering this amp. I'm all for versatility, but this is like telling me I can use my headamp in a speedboat or on a golf cart - this might be an excellent transportable amp for use in a hotel room but the last time I checked they had mains power, even in the 1-star hotels. It's one of the first questions I ask at the front desk - 'Do the lights work ?' - closely followed by a request for a room that hasn't been featured in a recent coroner's report or news broadcast. Of course, there's nothing to stop me from adding to the prospect of future broadcasts featuring said room when I set myself up with a 12V battery and a carton of beer - good times, eh wot ? I expect that there are states in the US where the emergency services actually have a code for that very combination. 

 

There ARE audiophiles who use sealed 12V batteries to power CDPs and the like but I guess that's fine if you live in your mother's basement or aspire to do so post-divorce. For the rest of us, the prospect of a good desktop amp costing less than a thousand bucks and requiring no further investment in tubes may well be the ticket - I look forward to those initial impressions.

Are you saying 5 A or 0.5 A @ 12 Vdc?  Misplaced decimal point...

post #74 of 103

5A

post #75 of 103

Actually, Craig informed me that the minimum required for Red Top operation is 0.5A at 12 Vdc.  The PSU he supplies with it is 12V 5A.  So both numbers are basically correct, as it turns out.

 

Do you know if the 3-pin jack and switch he includes with the current amp production run is for accommodating the ±24 Vdc tube PSU when he makes it available?
