Merci, stratele52
I've watched videos on re-coning subwoofers for cars and thought I would like to try doing it. Being on disability I have lots of time. Do you think I could re-cone these myself? What aftermarket speakers would be good to use?

Before power ON the amp use this gadget , easy to build and it save amp and fuse if electical short inside .
Usefull to start new filter capacitors too .

You need a 100 watts incadescent bulb .

Recone yourself ? I don't know how to myself . On my country , Montreal , Canada I know one of the best guy who make a great job , many vintage collector and tech go to see him ; $35 CND each speaker ; a deal . At this price I will not learn how to .

You may keep original speaker ( with no reconing ) apart and use aftermarket speaker .
Some like Weber.
BMW 2002Ti and vinyl may know more than me about after market speaker

OK Thanks. I'll get the originals re-coned. At the price I'm happy! Now I just need advice for the aftermarket set that I'll install. What do you think about the fuse? I'm Canadian as well.

I would go with model number 94 in the production. The #2 on the tube chart maybe the second amp of a production run. Dunno, for sure. But, the stamp on the chassis would indicate that the chassis in the 94th made. I suppose that Fender built, say 100, at a time. With the 94th chassis going to the #2 made amp? Better minds on this Board may know.

Anyhoo... Ma technique de langue de français n'est pas bonne. Le fer pour souder. Oui? :lol: :lol: :lol:

This afternoon I have a look on Guitar Vintage Price guide , last edition . 1965 Vibrolux Reverb worth more than $3,000.

I think the chassis was used for multiple models(experts here can chime in on this) like the Twin Reverb, etc. and while the chassis was the 94th chassis produced, it was used to produce the 2nd Vibrolux Reverb amp that year. So the first 92 of this style chassis would have been used for other models and the 1st Vibrolux Reverb then the 94th for my Dad's.

They wouldn't do a run of VR amps with serial numbers and then on the next run start at #1 again. It would defeat the purpose of a serial number. It's stamped #2 as it's serial number so I think it's the 2nd VR, especially with the late 64 parts and 501 dated Oxfords. But I'm a newbie so I could be wrong.

Thanks guys. I think my Dad will be surprised. I'll have to ask him, but I thought he said it was a Twin Re-verb. I wondered about the speaker size. Was I right about the serial number being #2 judging by the label?

I believe the #2 on the tube chart refers to the production number, but I don't know if there's any way to determine how many amps were made in a given production run.
This page :
http://www.ggjaguar.com/fendamp6.htm
indicates there were 850 made in 1964, so yours was around the 243rd one made in 1965. These are ballpark figures, there have been documented instances that prove this info is not always 100% correct.


The amp needs to be cleaned up but it's unmolested and all original. The case is in great shape with no nicks, dings, scratches, etc. Just dust and nicotine stains. I think a mouse may have eaten the edge of the label when it was in my Dad's basement. It's only seen about 7 years worth of my brother playing it in the last 45 years since my Dad stopped gigging around 1970.

I have analog and digital multimeters, a Weller WES51 soldering tool, and I only use professional grade solder and flux. I haven't worked on circuit boards yet but from restoring classic cars for 25 years, I can solder.

I got the Weller to learn to repair the circuit boards and change capacitors before they leak in some of my car amps. I'd like to do the repairs for the gratification of fixing it myself and the bonus of saving cash. But if the repairs are beyond my skill set, I would rather farm it out if I can afford too. I'll try contacting Stratele52 to see what he recommends.

The amp worked fine with no issues the last time my brother used it 10-15+ years ago other then the one blown speaker.

Then transformer that wiggles is the gold one # 125A6A and dated 606 - 4 45 in the pics. It wiggles side to side about 1/8-1/4".

That would be the reverb transformer.

I figured the best course would be to re-cone the originals and put in a nice replacement set. Any recommendations on re-coning, new speakers and vendors?

My Dad played classic rock but mostly just fools around when he plays due to his health. I'm just starting to learn to play, but my musical tastes lean towards players like Gilmour, Paige, Buckethead, Matthew Good etc. So what speakers would best suit this style? The guitars that will be used are a 67 ES-335 and a couple of modified LP's.

Thanks once again guys for the advice and thoughts.

You should be able to replace all the electrolytic caps in your amp fairly easily, with your background. Do all 'lytics --- main PSU, bias supply cap on separate board by lamp, and bypass caps on main board. Use as close to original mfd values as possible. You can go to higher voltage ratings, avoid using lower. Get good quality caps.


I believe the inside of your amp will look more like these pictures.
The main PSU caps:

Bypass and Bias cap:

The bias cap is in the upper left corner. The caps circled in green are actually dual caps (2 caps in one cylinder, sharing a common negative side. The caps circled in yellow are single caps.

Hope this helps,
vinyl

Good try, but I believe Fender used each set of letters and numbers for specific lines of amps. No interchange of chassis between models & serial numbers. At least, in the BF and SF era.

Check the link:

Note the polarity of those caps under the doghouse. All lined-up in same direction, unlike most 6L6GC Fender amps.

Just talked with my Dad. He bought it new for around $400-450 from what he remembers.

I was just guessing as a newbie. So how do you explain the #2 for a serial number? They wouldn't recycled serial numbers, it wouldn't make sense.
