The Amp Garage

I have no experience with these, but I’ve run across some NIB 6v6 and 6l6. Would love to hear your thoughts about using these. TIA.

Try to avoid measuring voltage when the dial is set for current. Fluke Has that internal mA fuse that costs a fortune.

Couple of months late, but here's what I use: https://www.mouser.com/productdetail/173-53122-e
Not currently stocked, but relaxed and grey 10ft.

Hummm... Bottom drawing stby circuit fishy to my eyes. Also, is choke used? Thx.

7189A's have pins 1&2 tied. 7189's do not.

Yup, I've power scaled/VVR'ed dozens of amps w/ success. I find them to work really well in the range I usually scale, which is above the halfway mark. Appears the fluxtone exhibits the same results. Doesn't seem like the components involved would justify the cost. Would like to know what it is that...

Another cranked tone at lower SPLs product.
Anyone out there know how these tick? They're REAL expensive and come w/ a box of active electronics. Their site doesn't exactly tell you how they work, just what they do.

What's the metal can at left w/ cap mounted on top?

About five years ago, I replaced the output tube board in my friends 5150 w/ an aluminium plate and chassis mounted sockets in PTP fashion. Wasn't too difficult. Also added adjustable bias. The power R in question is indeed 400R/10W, but I do like the choke idea. Nothin wrong w/ making an amp mo bet...

The cathode R for EF86 in the top amp is 22k, the one in the bottom is 3.3k. 220k vs, 100k plate R another difference. Should I keep going?

Flux remover will remove both fresh and stale sharpie markings.

Just bought some of these http://www.newark.com/vishay-roederstei ... -G-SKU-MDC

Gonna give 'em a try.

The track taper type and wiring of the control probably has as much affect on its operation as the track value. eg is full CW the most or least trebley setting? The old '60's JMI AC-30s were wired for least trebley at full CW, if anybody is interested. Has anyone noted how the Matchless type was wi...

Curious if anybody uses a sweep generator/comparator/attenuator along w/ XY function on oscilloscope to view sweep response of circuits these days?

Is this used w/ a microphone, pickup or both?
