Good morning!!!!

[KilroyJC]

can you twist it first? or does it have locking tabs?

It does not seem to have any sort of bayonet tabs - it just spins and spins. . . But does not move upward.

Is the tube pressed into a rubber grommet in the cover?

I think it is yes. See this used valve cover for Case 430

 

[KilroyJC]

It looks like this I think

That is what I sortakinda figger, I WONDER if the tabs have worn a groove and locked themselves in?

I think it is yes. See this used valve cover for Case 430

I may end up popping the tube out of the cover and work on it on the bench IWCTW

I may end up popping the tone out of the cover and work on it on the bench IWCTW

It may have a flange on the underside that will require removing the valve cover

Well, with my luck, it most assuredly does. . .

Yes that is a dual 15” ported cab, that has no mid or high drivers, nor crossover. It’s intended use is for bass guitar amplification. The other ones in these recent pictures are 3 way cabinets with a 12” woofer. They are a full range cabinet that could be used for anything, but are less efficient the the large cabinet shown. That will be used with a less powerful tube amplifier.
Modern class D amplifiers with switch mode power supplies are quite good and very light weight.

I am a retired audiophile, all of my efforts these days go towards the performance of music rather than the reproduction. But the difference between entry level gear and stratospherically priced cork sniffer stuff is no where near as great as it was in the past. Especially when you consider the vast majority of program is relatively low resolution streams and MP3’s.

To that said, I sold all my vintage Mac stuff to collectors that valued it far more than I did. Think multiple times what I paid for it new. That brings up a point, if you worked on your amplifier yourself you might seriously devalue it to a collector, regardless of how good of a job you do.

I never thought it'd be worth more, unusable than if I spent a few hundred and repaired it? There's a guy who fixed one "better than new" with supposed better caps and such. Hummm.

Good evening all. 43ºF for the start, 2.7 inch in rain gauge, partly cloudy, windy. Wind backed off during day, sky cleared, and high temp was 62ºF. Putter to start day, Bike ride after lunch, Low water crossing open, 3-4 inch water over road at crossing. We went to dinner late, Subway out of the multigrain bread, Manulito's too long wait, so ordered take out from lodge.
Bill good luck with spacers. Hope dump and town run successful. Hope you get your snow.
Ron 11 inch snow, Sassy will not like. Glad Comcast back up and running.
Kilroy sorry about prying a no go. You had not mentions it so I suggested it. How hard to remove valve cover or whatever breather is mounted on?
Spike glad no hail or tornadoes. Never got to see an Aardvark, nice pic.

It would depend if it was gone over by a cork sniffer approved guru or the previous owner. The quality of the repair notwithstanding. If you keep it, it’s a moot point.

Good early (Saturday) evening. The overnight low was 9C and it's presently 18.3C, overcast and calm. Rain/thunderstorms predicted overnight.

A lovely day was had with a 'clear run', there & back, to Ross. I even scored 4 Eccles Cakes at the Ross bakery! (which I'll enjoy over the next couple of days) [After all, I do need to watch my 'girlish figure'] The meeting went very well, although I did have to play Devil's advocate on a couple of proposals... <sigh> it simply needs to be done IOT have a healthy debate.

Home by 1530 and Penelope the pussybeast was actually glad to see me.

I spotted the 'Mad Horse Woman' so my early morning Lucerne 'biscuit' feeding of her horse is truly over.

That's about it, take care all.
