Those things don't really care, either seven or eight will be fine...

Probably work almost as well on six...

I should have been more specific. What do you think of the battery case for the price. I know the voltage/current will be fine for the application. I can't believe they show a picture of the battery voltage NOT under load!

B+ load isn't that important when talking battery portables, it's usually a couple ma at most... The average six transistor radio of the '60s was 5x that, those generally chewed up batteries every couple weeks...

I have one.  I use it in my Motorola 5A1.  Big Lots had a sale on Ray O Vac 9v's when I got it.

This guy has been selling these on Ebay for years and haven't seen any complaints about the quality of the product. If I had a radio that required these I would buy one. The cool thing is that its reusable.

A while back there was also a seller in Austria that had an eliminator that used 2 C cells and a switching power supply. I don't know how noisy such a unit would be. It weren't cheap.

Mez,

To answer your question, they look nice. As stated that seller and their products have been around for some time.

It's up to you. I typically don't go that route for something that isn't seen. I just tape together a bunch of 9 volts and typical snap connectors are wired in series to yield whatever voltage I desire.

This may not work in the application you are talking about, but I have one of those power supplies that AES sold years ago to use as a battery eliminator. Would that be less trouble than dealing with several batteries for what you need?

An update, the pack I bought nearly 2 years ago still is operating on it's first set of batteries, Ray O Vac industrial 9v's. It suprises people to see a tube based portable come on and operate like a transistor unit, as most of them are static displays with no power supply.
