Spec is helping me learn more about electronics and has been helping me to put together a decent electronics work space.Back in the day that supply was made, symmetrical power supplies were common. e.g. +-12 and +-15 for Op amp circuits and 5V was a common logic supply.
Today you still see 5V, but you also see .8, 1.8, 3.3. and 5V
We also see a fair amount of OP amps that operate on 5V.
Supplies like the Tek have a "tracking mode" where one knob adjusts th epositive and negative voltages. "tracking" means more than that. but for now, that's what it means. The Tek is three power supplies, not one.
So, the question is: What do you intend to use the supply for?
Oh by the way I have made the decision to get go down the path of an electronic engineer as my miss is studying programming so we would complement each other very wellGet the 10A they are all the same size and similar design and same price. You will be glad to have 10A

Unfortunately a lot of what you said just went strait over my head sorry I'm still painfully new to this, So do you think it would be better for me to get something other then the one that was suggested to me? I don't have much money so the less money have to spend the better but I will spend it if I have toHere's the "modern" version of the used TEK supply. https://www.circuitspecialists.com/spd3303d.html Now I did see it as the same price as the used TEK> Sigilent is EU.
They specifically added 2.5/3.3 and 5V as a switchable option.
Anyway, I should talk
I have a Fixed voltage (CV) power supply that is selectable 0-32 V, 10 A supply that's set for 12V. Total cost was like $15.00 USD in the 80's. Huge. I used it to fix car radios.
Got it broken. 3 inexpensive transistors to fix. Manual I just got recently for like $30.
Then I got a +12, -12, +5. (CV) Actually a fixed voltage supply with trimmers for about $15.00 - same time period. broke 2x 723 regulator IC
Then a 0-40, 0-3A CC/CV supply showed up free. Analog Meter switchable voltage/current Manual was $30.
Currently broken.
Then a 0-30 V 0-3A CC/CV with digital meters. No manual. Probably $50 ebay.
Commercial lead Acid 12 V charger tester. Free. Replaced a diode.
My father's "battery eliminator". It's basically a Variac and selenium rectifier. 0-6, 0-12V.
I have at least one of these https://www.amazon.com/VvW-Converter-4-5-24V-Rrgulator-Constant/dp/B00IOMSUNU mounted in a box. With 5.5/2.1 and 3.5/2.5 coax in/outs and an Adapt-a-plug output. It makes it easy to replace a wall-wart in a pinch.
The triple supply and an electronic load would actually be choices if I could "pick" them. Electronic loads are not cheap. e.g. https://www.bkprecision.com/products/dc-electronic-loads/8540-150-w-dc-electronic-load.html
I am trying to discourage the 10A single supply
unless you have a use for it or there is some other reason (price/performance)
Two uses I can think of:
Charging a lead acid battery (with locking diode)
Fixing or powering a car stereo
FINALLY WILL YOU STOP FOLLOWING ME AROUND ETO LIKE A SHADOW AND CONTRADICTING EVERYTHING I SAY WITHOUT GOOD REASON. I HAD TO LEAVE THE TRANSISTOR EQUIVALENT THREAD BECAUSE OF CONSTANT HASSLE FROM BOTH YOU AND AUDIOGURU - THAT THREAD HAS NOW DIED. I HOPE THE SAME THING DOES NOT HAPPEN ON THIS THREAD- DO YOU GET THE MESSAGE?
One has to wonder why you would join a discussion forum when you are not prepared to discuss, only dictate !
Whilst your opinions are as valid as those of any other member
you are so far up your own backend that the only thing that is infallible is your inability to break wind .. .. .. .. crap on the other hand seems to escape from every orifice !
I am very much a newbie, a novice or whatever you want to call it and I have had and continue to get good advice and help from many members on here including those you deride
.. .. .. I'm very concerned that inexperience leaves Justin in an impressionable and easily misguided position and in my opinion you've certainly shown him where the garden path is, if nothing more.
I outlined this to Justin yesterday, urging him to form his own opinions and pointing out that I had managed very nicely with some simple homemade equipment. Indeed, I also supported the choice of the £40 PSU .. .. .. you asked for details of my homemade equipment, which I sent but, because you failed to notice the acknowledgement of it's shortcomings in the details sent, you then embarked on an unnecessary critique ending with .. ... throw it in the bin and buy a £40 PSU from Ebay.
You may know all there is to know about electronics but precious little about talking to people !
Justin: If you want cheap parts just ask friends and family if they have some electronics that are unused or going to be thrown out. Thrift and used goods stores are good too. There are wealth of parts to be harvested from old equipment. Some of them are quite valuable particularly if they are obsolete and hard to find (like old plate variable capacitors from radios.) A lot of this stuff is nearly immortal. You just have to determine what the part is and nearly all of them have some labeling you can look up on the web.
I would but non of my friends have the kind of money needed to be able to go through electronics and most Thrift and used goods stores are to far away for me to travail to but I will keep it in mind. I should probably get myself a desoldering station so I don't have to worry about burning parts thenJustin: If you want cheap parts just ask friends and family if they have some electronics that are unused or going to be thrown out.
