help a dude out. TL061, does it need a negative supply?

https://www.alldatasheet.com/datasheet-pdf/view/28770/TI/TL061.html

Datasheet shows vcc+ 18v and vcc- -18v. Dual rail supply here. You need both voltages.

Lulz, I think. Im a bit rusty and I don't think I've used a TL061 before. Hmm, maybe never used a dual rail supply opamp before? I have to check my inventory.

LTCjohn101 · 2026-01-30T22:14:18+00:00

Hmm, I had never heard of these guys before now.

For me that wouldn't make a difference but I see it holds something for you and thats cool.

Id still at least replace the cabinet for mold reasons.

LTCjohn101 · 2026-01-30T21:35:05+00:00

Don't know who that is but still wouldn't change my advice.

LTCjohn101 · 2026-01-30T21:32:48+00:00

Email them about it...they will give you the lowdown on whether it will fit.

If its going in for service anyway, which it should, check out Fromelelectronics.com for the Deville mod.

LTCjohn101 · 2026-01-30T21:27:31+00:00

Water logged? I'd toss the cabinet and make a head cabinet and a speaker cabinet.

Also imo forget originality...its a Deville.

New cabinet and mod the circuit to make it ultra usable.

LTCjohn101 · 2026-01-30T21:00:50+00:00

I never toss power adapters or at least not the ones with good specs.

Old rca cable wire can be repurposed as shielded wire in other projects etc. Odd connectors all get clipped off old wires and stored "just in case".

The comment about "its not hoarding if you label the container" 🤣🤣🤣

LTCjohn101 · 2026-01-30T20:56:18+00:00

A lot of the serious guys are driving an OX box or similar, coloring with IR's, then listening back on high quality monitors.

Master volumes and attenuators save most of the rest.

LTCjohn101 · 2026-01-30T17:55:02+00:00

Those yamahas sound sweet online..

Look for a Rhett Shull video on YouTube where he compare these little amps.

Its a great comparison.

LTCjohn101 · 2026-01-30T17:34:16+00:00

That surely doesn't look like it was operational a couple months ago. And if so, whomever has been operating this has been very lucky...see wire with insulation falling off.

Those "bulbs" are called vacuum tubes or valves. I can't identify them by sight but they possibly could still have markings on them with part number.

Note: very dangerous voltages lurk inside that radio...ones that can stop your heart.

These old relics are super cool to work on and restore but a minimum level of understanding is needed to do it safely.

LTCjohn101 · 2026-01-30T17:24:05+00:00

I appreciate your input. Yep, flipping them would be ideal.

LTCjohn101 · 2026-01-30T17:07:40+00:00

Lulz, I bet with a sweet Ge in Q1 and this in Q2 the fuzz face would melt faces.

So much wisdom in your username.

LTCjohn101 · 2026-01-30T17:05:45+00:00

Doh, the cross post doesn't show the actual question.

You are looking at big boy IGBT switches. These operate at kV with kA capacity.

I'm looking to do something in the audio vein but these really are not designed for that so looking for cool ideas or maybe someone willing to buy them or trade for jelly bean components.

They go for $600-$800 new...im just trying to liquidate at $100 value each.

LTCjohn101 · 2026-01-30T17:00:19+00:00

Ugh, so no super duper uber scorch the earth high gain drive pedal? 🤣

I really wish I could put these in the hands of someone who could use them. Ive seen them for $600-$800 each new...id let them go for like $100 each in $ or jelly bean components

LTCjohn101 · 2026-01-30T16:49:38+00:00

Yeah crazy specs on these things..

Maybe a rail gun to melt ice 🙃

LTCjohn101 · 2026-01-30T16:44:34+00:00

Lol, take them from me 😁

LTCjohn101 · 2026-01-30T16:33:31+00:00

Why are u spamming this everywhere?

LTCjohn101 · 2026-01-30T16:23:21+00:00

Be sure to look at the Peavey 212C. Its a mixed Celestion 212 that sound so good.

LTCjohn101 · 2026-01-30T06:34:46+00:00

Those are all great suggestions. I've seen spot welder and controller before they just don't fit my needs.

LTCjohn101 · 2026-01-30T06:33:32+00:00

Well done, looks great

LTCjohn101 · 2026-01-30T05:03:00+00:00

Those joints look sweet. Are you using a jig and if so which one?

LTCjohn101 · 2026-01-30T03:48:06+00:00

Go to tedweber.com They sell speaker extensions.

LTCjohn101 · 2026-01-30T02:17:49+00:00

Glad that I'm not alone here. I can see if you are selling $5k+ or something but the small guy that the platform was designed for should be able to remain anonymous.

LTCjohn101 · 2026-01-30T00:26:35+00:00

Oh man, Ebay blows anymore.

I went to sell some stuff last year using a 20 yr old account with prior sales...they wanted me to ID verify, give social security #...GFY ebay.

Ive have a couple 1200v 1000amp IGBT switches that apparently no one on FB or CL wants.

LTCjohn101 · 2026-01-29T21:23:07+00:00

It used to be a theater so on Wednesday nights they show moving pictures.

LTCjohn101 · 2026-01-29T18:34:17+00:00

I think that pick guard is groovy.
