Yeah, but I tend to work that way. See my bench in post #49. So it looks good to me!
For a well stabilized AC Voltage on the bench:
Philips 7776 AC Voltage stabilizer, max. load of the saturation reactor = 2,5kW
the apparatus have 5 tubes and a weight of 160 pounds.
Input any, from 180 up to more then 250V AC,
Output 220V (adjustable) stabilized <0,1% between nothing and full load.
Martin: Doesn't everyone have a Saturation Reactor?
Great benches on display. Martin You have Tek Scope Heaven beautiful. Seen your posting on EEVblog. Given me ideas. Have to clear part of the house being used for storage to set up my spot.
If Martins collection is any indication,I wouldn't be surprised if he has a Nuclear Reactor.....
The bench is part time, as I reside in an RV. I have a lot more test equipment that won't fit beyond a limit. The little BK scope works fine for audio. Also have a Tektronix 453 DOA, that's another story
Sorry to hear that AudioLady. Welcome to AK.
You mean the switches?
-The red one is the main 110v power for the monitors and the PC power supply input.
The four small switches:
-PC Power supply power-up signal
-5v Power to the 4" LCD monitors
-5v Power to the SD media players
-12v "remote power" signal to the car amplifier
The jacks on the bottom row are inputs for the monitors (HDMI, 1/8" Stereo audio, composite, and 2 more composites for the 4" LCDs). Speakers for the main monitor are mounted down-firing under the cabinet
what means DOA please?
453 is a cold Classic Tek, no IC inside. Full 50 MHz. Only in the High Voltage part are 5642 rectifier tubes working, and in older models nuvistor inputs, newer 453 and 453A have FET inputs.
I like them the compatible scope mobile is the K212
Typically, DOA means Dead On Arrival. Kaput. Not Operating.
Another reason I like the old Tektronics scopes is that they help keep my shop warm.
That's why a 547 is my ''winter scope'', a 515 for ''spring and fall'', and a 2235 for ''heatwaves''
My current workspace is a bit temporary as I just moved into a new (to me) house 6 months ago and have numerous remodeling projects ahead of me. Restoring a receiver now and again is a good distraction from other stresses. Eventually I’ll frame up something a little nicer and hopefully get more organized...well maybe I’ll just settle for nicer.
Wanna see my rack?
That's just some of my equipment. I need more space.....
The kitchen counter or the dinning room table most of the time. A Marantz 5020 cassette deck in for service and new belts rat now lol.
Here's my setup. Presently working on a 1998 Fender Vibro King:
Oh yes. I once worked at a radar site that had huge air conditioning and heating systems. They were "played" against each other to provide very precise relative humidity control.
Every now and then the boiler would trip off during the night, and at 7:30 AM starting time the place was a cold storage meat locker. The A/C had to stay on so we could support the range.
We would all scramble to the supply room and check out 545's. Once I had three 545's and a 575 surrounding my desk.
Tek made the best scopes ever, and obviously were quite versatile.
Love working on guitar amps. Usually failures are related to the fact that they get moved around a lot. I know at the end of the gig I didn't place the amp back in the vehicle with the same care that I took it out.
having all that stuff, would be assume
it just not right! all i have is multi meter and a solder iron.
I see that I am not the only one who works standing up, not sitting in a chair (I see many benches with shelves or things under the table, no room for legs and a chair)
Yeah, but a multimeter covers about 95% of all the troubleshooting I do.
Just need the other stuff for signal tracing, waveform analysis, and AM/FM alignment.
