You are being pedantic. The OP admitted he didn't know much about amps. Up inside the socket the edges of the holes are sleeved with the contact.

A valve cover is a cover, I wouldn't necessarily call it a sleeve but if it makes you happy. And why would you need a small insulated probe to reshape the cover?

Well as you insist on continuing to be pedantic the thing you are calling a sleeve is actually a screening can or valve shield.

A sleeve (in English) is often used to describe something that covers the outside (often of a cylinder) or the inside of a hole or tube. In this instance I used sleeve to describe the cylindrical contact receivers inside the socket.

I can appreciate that if you call the valve cover, screening can or valve shield a sleeve this would cause confusion and (as I don't call the valve cover, screening can or valve shield a sleeve) this wasn't my intention.

After reading your post on the socket sleeves I tried googling it but not much info on that. Anyways, don't fight over a noob question, we are not worth it :lol: Tube amps are worth the effort though and this little amp is great for my apartment with strict neighbors.

Just called Fender and they are very helpful. After buying a two guitars and two amps, it's the first time I called and they are real pros so that's nice. Almost makes me want to buy a deluxe reverb for my tiny apartment :oops:

They've got some local repair shops that they work with so that they can give Fender an expert diagnosis and then Fender can figure out what's the best solution, whether it's a replacement or doing the repair etc.

I'm sorry if my description caused confusion (and for any subsequent discord :roll: ).

Delighted to hear that things are moving forward for your Champion 600. I agree they are a great little amp for home use. I have 2, one stock and one modified within an inch of its life. The speaker change is very worth while and makes a big difference. Ditching the cheap valves is also a great move.

I dig the look too. Paid the same price for a bad 15W solid state from Marshall years ago (not putting all solid states, just that one). I know you can give a Hendrix anything and he'd make it sing, but I need all the help I can get.

You and me both. I bought my first Champion 600 a couple of years ago and thought "That is the sound I have been looking for." And it is so convenient. As a result I have bought another three 5w valve amps since - so I now have two Champion 600s, a Bugera V5 and a Princeton clone.

We seem to be seeing a big rise in popularity in small valve amps now with offerings in almost every price range but I agree that the 600 has a certain something. It is small enough to be discrete but large enough to just accommodate an 8" speaker.

FWIW... I read that the earlier versions of the Champion 600 reissued amps used noisy solid-state diodes. To compensate Fender bypass them with equally cheap caps. If you replace the OEM diodes with good quality UF4007 diodes, you can remove the bypass caps and get cleaner, better DC.

I know that you'll be returning the amp or finding a tech. You may want to run this by him.

Yeah 5w is really enough for home use and I even like the boxy sound if that makes any sense. I used to play on bigger amps years ago (Blues Deluxe) but forgot the feel/sound since I stopped playing for almost a decade.

When does your Champs start breaking up? I can rarely go past 7 on the low gain channel or 5 on the hi gain with full volume on my Les Paul because of my neighbors but it doesn't seem to overdrive to me or maybe I don't dig enough on those strings. I have a nice OD pedal that I just got, the Od-3 by Boss and if it looked more boutique people would be paying $200 for it.


@BMW2002Ti I noticed that there is a hum but it doesn't bother me too much to be honest, don't know if that's the same thing than what you're talking about. It would be an improvement that's clear though, thanks for the technical tip

I have a couple vintage Vibro-Champs (BF and SF) & one 1949 Champion 600. The VC break-up around start to break-up around 5. This is with aftermarket Weber 8-inch speaker. The Champion 600 starts to break-up even lower volume. Maybe around 4. This amp current has 6-inch speaker.

Honestly, the ancient Champion makes a tone to die for --- if you like brown tone with smooth harmonics. It uses a pentode 6SJ7 input-driver instead of the typical 12AX7 of later tweed era Champions.

FWIW

GC has the 600 on sale for the New Year, for $149.....Hard to pass up @ that price, inferior as it may be to the original.
