One of those early UHF channel converter boxes for early TV's back in 1952. Looks neat making a tube guitar amp out of it. To drill holes with the proper spacing you can also use an automatic spring punch available at most hardware stores. Just a sweet and excellently designed amp build there Terry.
Thats really cool Terry and its a one of a kind amp and would build something like this instead of a kit any day ,Im going to join your Patreon soon because I have been watching your for about 4 years or so and really like what you do ,especially when you visit the Ham fests ,I keep a towel under my chin to catch all the drewel because we dont have them here in Frederickburg Va if we did I would be living outside in the shed probably lol
Nice little jewel there Terry..Great build, and seems minimal component wise..But those transformers would break my bank..! Top video as usual..Ed..UK.😀
Hi, how did you set the bias since the power transf sec shows 480V?, 5F1 layouts over there shows it uses around 650V/700V high volt (hammond list). Did you set plate voltage decreasing the plate resistor?. My english isn't that good sorry, I'm a self-learnning guy and I'd like someday to build a 5F1 circuit. What a great videos you do, I have seem/downloaded many of them.
Some "techs" have all the fun! O' to be a fly-on-the-wall at the famous "D" Labs. Keep these videos coming .....

The amp sounds so good, you are making me think about doing my builds without a tone circuit.
Wow, would love to see you do more of these .
I have more in line, just need time!
Sweet build. Always looking good D-Lab. Thanks alot.

Great project. The trick will be finding the RCA cabinet for a reasonable price.
Yes, back in the day I could find them for 10-25 dollars. Now they get about double that. But its still cheaper than making one!

Yes, the transformers are pricey. You can substitute. e-mail me and I can send you a schematic
Those fifties radio cabinets are great looking!!
Love it! Nice use for the old, useless UHF TV convertor cabinet.
Very nice, I built a 5C1 amp!!!
Highth, excsetra, I love it.
Thanks! Terry🎶🎛
Love your stuff. Makes me want to build another one. Keep up the good stuff!
Great Project - This is something I could see myself doing!
I would be glad to help you complete this project
Great looking build. I noticed that both transformers are oriented the same direction and it is still quiet.
Pretty cool!
Love it, wish I had the electronics skills to build that amp.
What a beauty!
Oh yeah! Great sound!
A Fender twin with just 1 volume control must be considered?
Very nice build. 73
How does it look in the dark?
How might you add a headphone jack to this setup ?
Why not give a try of a 5C1 with the 6SJ7, it sounds great and with a separate cabinet that metal pentode tube is less microphonic.

D-Lab,How do you add a headphone output?
AWESOME!!!!! What's the wattage output?
Approx 4.5 watts at the High voltage in this design
That sounds great!
If no tone control, how do you decide what the eq curve should be?
Just build it like Fender did, Most use their guitar tone controls
Terry
Isn't that Tony playing on that looper? And the looper, can you give us the name of it?
Hello, Yes, Thats Tony C. The looper is a EH nano looper 360
Love it!
how come you didn't just use a switched pot, save on drilling the extra hole?
So this amp would work on a Marshall 4x12 just as long as the impedance matched?
Yes, sure would
Cool. @@d-labelectronics
Where do you get your center drills for removing rivets?
What size? I am so sick of rivets spinning on the drill tip.
ebay is a good source
@@d-labelectronics what size?
1/8" center drill
@@d-labelectronics I'm lazy, do you have a link?
@@d-labelectronics Awesome, thank you!
Gorgeous little thing. At all worried about heat dissipation?
Nope, Back is wide open, Have made many of these, no complaints so far
@@d-labelectronics Ah. I didn't realize you leave the back off! Thank you.
Nice simple tube amp, but there is no tone control for music reproduction.
Nice work! Thanks for the look.
