How long would it last?
Is it possible to remove the batteries(easy?) and charge them with the external charger and put them in?
I believe I read that the batteries are stuck in place. Get an external battery pack.

The batteries are glued to the board but they can be removed.
I read on the LISA Website that The internal changing circuits do not disconnect the internal batteries after specified of time so I plan to use the external 9v charger.It's safer IMO.

Anyway,I will try using the Alkaline 9V tomorrow.
Hopefully it won't explode.

Wait, so the charging circuit does not trickle charge after the batteries have reached their capacity? What about the Expidition modle? I have ruined batteries that have been overcharged because I am not always going to remember to unplug something. I have batteries right now with too much internal resistance because of my goofs.

I am going to get one of these and solve many problems both here and when i travel overseas doing work:

You can get these on ebay at a very good price and with the variable voltage and 4000mA (4amps) of storage the electronic device, depending upon it draw, should run for some time. There is also the extra battery 3450-10 that an ebay seller told me he can sell for 78 buckoos.

First of all the batteries are not glued to the boards. They are fastened with reusable double sided tape. The trickle charge has a windows of 12-15 hours for a full charge from depleted state.

Great, so it trickle charges. I look forward to more impressions or reading of more impressions as time goes on. I like the idea of a discrete output section, which should bring the amp to another level.

Nope. That's what Brad gave me from the beginning. I'd like to have a black ones, though

I'm sorry, this image is just freaking comical

DO you have this AC adaptor as well for the Exp LISA version?

My Expedition is due tomorrow, and yes I'll be using that same AC adapter I've been using with the Standard Lisa III.

Sorry Flashbak,

When I order the amp, does it come with an adaptor? or I have to order from elsewhere?

Just want to jam in here. The LISA III will NOT come with an adaptor. You will have to buy your own, or use one of your existing regulated 24V DC supply with the right plug. I have tried the PSR (the power supply designed by Phil for the Pocket Reference II) and it works well, though I am not sure if it has the sufficient power to charge the Expedition within reasonable time.

If you decide the LISA III is the right amp for you, I would highly recommend you get the LISA LAB POWER (LLP) PSU which was designed with the LISA III in mind, and according to Phil, his best PSU design to-date. The LLP is universal voltage. Since it use standard 2.5mm centre positive plugs, you will also find it useful in other applicables, as long as current draw is less than 500mA (which is quite a lot).

jlingo,
This thread has alot of info in it. Please look it over since part #'s for the AC Adapter as well as a few vendors who carry that Elpac adapter were listed should you choose to go that route.

I have some queries regarding AC Adaptor and charging the amp.

1. How long does it take to charge the standard Lisa III with the Elpac adaptor?

2. Is it possible to use the amp while charging (using the Elpac adaptor) or have to be turned off when charging?

3. Finally, would be ok to charge the batteries using a separate 9V battery charger, which means taking out the batteriers from the amp?

4. Finally, I've heard some contradictions regarding using regular 9V alcaline batteries. Can I used them with Lisa III ?

Let me try :-

1) I understand the LISA III uses a slow charging circuit so a safe bet is to allow 10 - 12 hours (guessing).

2) Yes, I spoke to Brad who told me that the 24V d.c. supply will power the amp direct AND charge the batteries at the same time.

3) Yes, theoretically. But as the design illustrated the batteries are not supposed to be taken out frequently. Strongly recommend you charge the batteries with them fitted inside the LISA III.

4) Apparently this is not a good idea, because the LISA III is designed to run on rechargebble, not off-the-shelf alkalines, which may have different internal impedance and voltages. Also, depending on what alkalines you are talking about it may not fit due to the tight clearances inside the LISA III (and not all 9V batteries have precisely the same size). Even if it seems to be working, I am not sure if this may affect the sonic performance.

I may be wrong, but I personally would not risk this on a $500 amp.

Some quotes from PPL regarding battery charging

This is extracted from a posting by PPL at TriadAudio in early August 2007 :-

Quote:-

The Elpack will operate and charge both the XP and standard LISA. The internal changing circuits do not disconnect the internal batteries after specified of time so it is advisable to disconnect the charger from the standard lisa and perhaps operate the unit on batteries for 30-60 Min to deplete any slight overcharge that may have happened under very long intervals of as only use, this is more than 30 days. LISA takes a full 15 hours to charge the batteries on both the standard and Expedition models.

The same apply s to the optional LLP (Little Lab Power)LLP power supply.

UnQuote.

Hope this is helpful.
