Thread: Toggle Switch for Thunderbird Amp

  1. #1

    Toggle Switch for Thunderbird Amp

    I've had a '67 Thunderbird for a long time. I had to totally rebuild the cab. It's a great amp. However, today, I was moving some boxes, and snapped off the STANDBY toggle switch. Never realized how delicate that thing was!!! After all those gigs and moves, just walking by it with a box did it! :)

    Anyway - is there any chance that there is a replacement part somewhere?

    For those interested, here's a pictorial of the rebuild - if you look at the 9th picture - those white switches on the far right...

    Thanks.

    Don't know if these are the same, but, http://www.ebay.com/itm/like/3507892...chn=ps&lpid=82

    These plastic switches were not the best; on my Thunderbass, all 3 were broken off. I'd suggest, which is what I did, replacing both of them with 2 quality metal toggle switches. Then you won't have to worry about them snapping off again.

    Well, thanks for the reply, and the link. My 2 issues - that will probably ease up when I realize that the glue won't hold :)

    1 - Coming from China.... Never like those auctions.
    2 - I know I could replace them - however, I've tried to keep the amp 'looking' stock.

    I realize, I have a different speaker, and the entire cabinet was built from the ground up, but... It 'looks' original.

    If the glue doesn't hold, and I can get the switch into the non-standby position, I'll just keep it there..

    Other than that - even though I have the schematics - are they just simple SPST switches? I don't remember.

    Thanks again.

    Yeah, I avoid the overseas auctions if I can; I don't know if you can find them otherwise. I checked both AES and Hoffman with no luck. You might check Mouser.

    On my TBass, they were DPST, so you'd best check your schematic and what's in there now. Guild tended to shop the bargain bin for their amp parts, so you never know what you'll find.

    Here's a picture of the broken, and not broken switch. As I thought, glue did not work :(

    Need to see the inside to tell the type of switch (SPST, DPST, etc.)

    Chris you rebuilt the cab with what, pine, instead of the original particle board, yes? Did it sound different? I always wanted to build solid wood cab for my thunder bird, so I could take it out to gigs without wondering when it would shake apart.

    I'm glad you asked! :) Yes - Pine. The old cab had been in a wet basement for 30 years. I had no other option. The tolex peeled off like a grape. So, I decided to NOT use particle board. I have a friend that's a 60's Fender fanatic, and said to him, "I can't believe they made these amps out of particle board in the 60's!" His answer was, "You know, that could be part of the sound..." I never thought of it like that, but, I don't care. I never heard the amp before, and it wasn't my intention to have it sound like anything. I wanted it to be solid (which it is) and allow me to use it for gigs (which I have). The speaker is original - my friend found a basket kit (he had a reconing business for a few years) and for the 8" reverb speaker, I just went with a MojoTone.... Last year, I had an amp tech go through it and replace all the caps and parts that could become troublesome. I mean, in its defense, with the exception of the tubes - which were removed when I got it - and the speakers - I did ZERO repairs on the electronics. So, that's a well-built amp in my opinion. It's EXTREMELY solid, works 100% - I bought two switches today, and I'm sure the amp will last another 47 years :)

    TC,

    My amp's been in storage for a while (it was crackling a little). If I had to describe why I liked it, I would say that it sounds as good as a Fender, but it isn't a Fender. I liked my 'Bird with the reverb on because the amp sounds a bit plasticky without it. I thought the vibrato was good, but not as great as the Guild Thunder 1 RVT amps. I never really explored the best way to mic that amp, either. Those two speakers make it a little problematic. Two mics, one for each speaker? Or one in the middle?

    What kind of music are you playing on your rebuilt TBird when you gig? I always thought of it as a jazz amp you could play rock on. What amp did it take the place of in your set-up? What kind of guitars do you use with it?

    I usually gig with a maple necked Strat using vintage style pickups with a 5% overwind through a Deluxe Rev/Princeton Rev. 5-10 years ago, I used a Vibrolux Rev and 15 years ago, I used Marshalls and Hiwatts. A second guitar used to be humbucker equipped. Now it would be a nylon acoustic electric :)
