'36 Gibson EH 150 Part 2 | Deep Issues and a Closer Look

Getting to the bottom of everything the amp needs to shine again, including genuine authentic Mad Scientist stuff.

(uploaded again so when Pt 3 drops in a few days everything will make sense - it took a while to get the speaker reconed)

Once again it's Mercury Transformers to the rescue😃👍
Am glad they are around for us😎👍👍
This amps life saving needs being addressed, the final sound check is anxiously anticipated 😁👍

[sgt.grinch]

Once again I am impressed with your work. I like your style and ability to repair any amp.

[MichaelSmith-rnqw]

Dang, Lyle closing in on 60K subscribers! I remember the slow climb to 5K. I have an Eminence speaker with that same tearing paper-buzzing sound, mine is definitely no good (and not worth re-coning). I guess it's technically possible to replace the voice coil without doing a complete re-coning. I may take the dust cover off when my replacement speaker arrives next week, just for fun.

[rlsmith]

I like your real world testing. Thanks for fixing the old amp and producing the video.

For those interested, "A field coil speaker is a loudspeaker that uses an electromagnet instead of a permanent magnet to move its cone."

[michaely]

Look forward to completed repair and demo.

I can tell you as having played through a completely original 1937 EH150 using it's matching all original ES-150 guitar, the amp you are working on sounds nothing like what I played through, and I didn't play it one time and never again, it was weekly for several years as I was renting a house off of the 2nd owner of the guitar and amp, and he blessed me with allowing me to play them (deepest "V" neck ever, but also damn comfortable!) the amp sounded SO MUCH better than the one you are working on, I would suspect changes to the circuit or other fuckery.

[UncleDansVintageVinyl]

This is such a cool old amp, and I want to thank you for returning it to service.

[joemcgraw]

Interesting the field coil isnt mounted on the speaker but alot easier to work on that way im sure, nice sounding amp, thanks for showing stuff you use for repair I usually take notes especially on your irons

[maxvockner]

What a cool trip from the beginning of Amps. ❤

[retread]

The collector value on this amp is huge. Playing through it would be like driving a Ford Modal C. A very fine place to visit but I wouldn't want to live there on a daily basis. YMMV.

[jonnybeck]

Yes those 6N6's are as weird as is possible...
Maybe you'll discuss this a bit more...?
I suspect they are a pain in the (where you sit)
...oh and thanx Teach

[maxbialystock]

From all my brothers and sisters in the dumbass guitar player world. we thank you wizard for keeping us sounding fabulous.

[jamesunderhill]

Oh man, this is going to be a DOOZIE of a fix. These are the kind of amps that REALLY need saving, its just a pity that it wont be a origional as it could be given its age

[FluffyDog]

Interested to know if you’ve ever seen / messed with the internal of a SilkTone, and what your thoughts are if you have…..

[timcook]

We need one more like - we would then have 335 🙂
