What electronics have YOU fixed lately?

[Rick330man]

Had four of the six tubes (three 12AX7's and one 12AT7), so I ordered the two EL-84/6BQ6 to complete the lineup.

This may just be a typo, but did you mean 6BQ5? You mentioned EL84/6BQ6. I use EL84s/6BQ5s in lots of my guitar amps, so I was curious as to whether there is some other EL84 equivalent besides the 7320s and7189s that I might have missed.

On my end, my repairs skills are limited due to injury. However, I did recently open up and re-bias my Monoprice 15 watt guitar amp after swapping out the power tubes. The amp - which is a Laney Cub12R with a different facade - came stock with Shuguang EL84s, which sounded O.K. despite being biased cold (idling around 45%) from the factory. Several different brands of EL84s got the tone test - including Ei, Tesla, JJ, Gold Lion, Sovtek and others. The winner: a pair of old, 1980s production Soviet military 6P14P-EVs. I set the bias at 56 and 60%, respectively at idle. My plate voltage was running around 292. At these values, these power tubes should outlive me.

I purchased a Connex 3300HP on eBay a couple of weeks ago for dirt cheap. Somebody gave it the golden screwdriver treatment. It didn't transmit or receive. I fixed the radio and aligned it for this truck driver I know. It was his birthday on Oct 5th so I gave it to him for a birthday present then so he could put it in his big rig. I converted it into the Big Betty Boop "Purple Nurple" edition...lol. The guy loved it. Here is it before and after I was done with it.

Replaced a 2 pin charging port on a Snap On Tools magnetic under hood light. A 2 pin aviation connector and socket fit perfectly and handles 5 amps!

Well, today, I repaired a 4 transistor Palomar 400 amplifier for a fellow that I have done work for several times.
I replaced all 4 SD1446 transistors with original ST-Micro parts.
The output combiner resistors were also toasted. Replaced those also.
Simple repair came out just fine and amplifier performing very well.

Them Beers must not have been open & they must have been very small if all Three of them fit into that little control box? Wonder why somebody would have put any Beers in it much less Three? LOL hehe haha {:>) I could not help myself Mudfoot.

Put a New 9 volt batter plug in a TUP9 D-104 that I got from an estate.I can't figure out why they cut the other one off? It still needs a bottom cover but that's not a big deal.
