Circuitmaker circuit help

I have a simple two transistor multivibrator circuit that wont produce an output waveform when simulated in Circuitmaker 2000. The actual constructed circuit works fine. If anyone has an idea of what the problem might be I be pleased to hear from them.

The Circuitmaker file is on alt.binaries.schematic.electronic

Ho humm...simply not true for "linear" oscillators. I have several in my SS examples. All start without a kick. I have rarely found the need to kick start such oscillators.

The standard simple transistor multivibrator is a "relaxation" type oscillator, with a stable DC state. Numerical noise won't get it going.

or....just use a pulse with a long on time for the power supply.

Thanks for all replies. Multivibrator now oscillating and getting the expected waveform.

JT guessed right. If you place a .IC at the base of either transistor in your circuit, it oscillates, as shown here:

Since you gave yourself the name "Alt Beer", where do you get that stuff? AFAIK it's really only popular near the city of Duesseldorf or about 6000 miles from here. Can't buy Alt Beer :-(

Sometimes micro breweries out here try but it ain't the same.

They do very well, one never gets a bad beer. I don't know how long they store the product, but the two micro-breweries I frequent in Cambridge have multiple brews on tap, and they're great. The several small local beer companies also do well with their bottled products.

Joerg -- I'm about 60 miles due north of Sacramento. Do you live in Sac?

Well, there's this one:

What is the current state of microbreweries?

Last time I lived near one, in the late 80's (hertfordshire) the owner had a difficult time maintaining consistancy between batches, some barrels would last for days before going off, some much longer

Ah, which Cambridge. Westpondian or Eastpondian?

martin

Do they top ferment or bottom ferment?

Hello Martin,

Near Sacramento, California, they are doing well. Most are growing and quality is consistent. I like the taste of their brews a lot more than from any mainstream breweries in the US. Unfortunately one micro brewery, actually the closest to us, seems to have closed down. Sad, since that was the place where we used to fill up our growlers.

Regards, Joerg

That would be Grass Valley. I've had the 182 into Cameron Park Intentional numerous times to fill up on mogas.

Jim

Hi Joerg, Duesseldorf. Went there for a few days and drank a number of Alts while visiting local Christmas markets. Not sure if its available in the UK though.

John

Hello Jim,

That would be Grass Valley?

I am in Cameron Park, about 30 miles east of Sac on Highway 50. Really close to the CP airport runway.

Regards, Joerg

While I lived in California, I dearly missed my Altbier. But then I found a bearable replacement that is available at least in California in the same quality and taste: Becks Dark. Yummy.

Not saying that I would pass on a micro brewery though :-P

Hello Matthias,

Yes, it is yummy. About 15 years or so ago I was always a bit grumpy when I couldn't buy Becks Dark in Germany but only in the US, despite the fact that it was brewed in Germany. So once in a while I took a six pack on a flight to have the Germans try it.

In an effort to deal with my own beer addiction i have decided myself to start a microbrewer. Only problem is that my brand new stainless steel fermenter which i had custom designed and manufactured only holds 100litres....I already want bigger....
