Invader 60 valve amp, novel layout.

This one has been in a damp shed for a while, so will need some drying out and cleaning, because it smells weird.


Knobs on top of the chassis:


Board mount stuff, boo:


Tiny output transformer isn’t my bag, also no impedance selector, hope this isn’t another 100v line job, doubt as has ‘high gain’ inputs.

And the underneath:


Pretty neat wiring, sort of looks like hadn’t really got the idea of the whole PCB thing, with putting loads of wires over it.

Kenwood KD 5330 Direct drive turntable.


This was curbed near me, picked it up and put in my to do pile, reasonable quality 70s Japanese turntable. Needed one since I have a bout 500 records and no player currently. Note on it said in need of attention.


Check over inside it mostly just dust in there, nothing electrically upset. Here’s something I’ve heard of but not seen before: Wire wrap connections:


Clean up and a head shell/cartridge borrowed from my housemate, and it seems to work, but I lost the screws that hold the bottom panel on and it is missing its feet (well, all but one)

Newer Vox AC30

This came in with intermittent cutting out/volume loss. With a gig coming soon, it was a while U wait fix, so didn’t mess much with taking photos. Outside, looks like a Vox AC30. New variation on the tinfoiled fuse theme inside:


Pretty sure is a guitar string. Makes sort of sense.


Inside is all horrible PCB at angles and tons of push connectors. All put together in a really awkward way that is probably homage to the originals. Bust solder joint on the master volume appears to be issue, resolder that, and a few other likely candidates, replace the fuse, gave it a go, seems to work, didn’t fancy trying to extract all the PCBs anyway. Cleaned all its sockets too, vertical inputs is ideal for dirt to fall into.

Buman Power Pak PA preamp and Slave amp


Modular rig, you can also get instrument preamps and chain as many of the power amps up as you require.

This one came without valves but had work done fairly recently:


Preamp photo was a bit blurry,, can’t tell from camera screen, and I’ve put it together again now:

pre guts

Solid state board runs the reverb. All but one of the pre valves in there were duds. Since two other of these have both required new pre valves when I’ve gone over them, have a suspicion something in these is eating them, but don’t know what. Pointers would be appreciated. On first try the reverb knob just gave a nasty whistle. tapping stuff with a chopstick to try and find it, and a good ding on the reverb tank ‘fixed’ it. Not the issue won’t recur, so guess have to call it fixed.

Selling other stuff

Realised should stick other non amp stuff here too, don’t miss previous post with amps for sale, as well as other sales details.

ESP LTD H100, Sold

Joodee Rickenbacker copy / rickenfaker, really nice Japanese 70s copy SOLD but get in touch if you are after rick copies.

USA made Musicman SUB, neck looks well worn, feels nice, apparently was a finish thing with them, body finish is super tough though. Active, really nice, just had to resolder some of the PCB as detailed in another post. SOLD

Boss Metal Zone MT2 distortion pedal. £35

Boss Mega Distortion MD2 distortion pedal, also £35

Simms Watts PA200, that I totally forgot about for the last post, SOLD

Japanese Companion solid state amp, old and stylin, SOLD

Burman Pro 501 combo, not convinced I want to sell, but not as useful as the heads in practice, £600

Selling stuff.

Edit: Shipping for amps to UK will be about £20, EU countries will generally be about £40, Norway, since I’m getting tons of hits from there, is about £60, some of the heavier amps (200 watters) might be a bit more.

Could do with funding Christmas and suchlike. Most of this has been on ebay, cheaper here. Offers on stuff considered, especially if you want multiple things, or want unvalved to put your own it etc. I can ship worldwide, collection is ideal though. Paypal or preferably bank transfer accepted. olifoxen at hotmail dot co dot uk. If other stuff on the blog has caught your eye, ask, got tons of things waiting for me to fix I could move on potentially.

Hiwatt 200 PA Been cleaned, and valved, just used an open jack plug to bypass the force you to use two cabs arrangement. Works fine with no noise. £1100

Italian MAC and here for inside pics SOLD

Vampower PA, not finding the front shot, might be my bad tagging, but the insides are here. And a pic from elsewhere. £450

Nolan 100w, insides in the link above, serviced by my mate, really nice sounding amp, £500

Stak by MJB Electronics stack. 130w head (4 EL34 and nice transformers) and a 18″ W horn cab. I spoke to the guy who designed and built these, the cab was ‘designed’ by sending his carpenter mate to the local music shop showroom with a tape measure, looks like he picked out an Acoustic 361 to measure up. The head is fairly simple Fender style preamp, simple but made really well, which is the best way for valve amps to be. This is mostly for sale just to lose the cab, takes up loads of room, but too much of a shame to split them. The original Gauss driver with a voice coil rub will be included, there is an Eminence 18 in the cab currently. SOLD

Carlsbro 100 TOP. This wins the prize for contrast between how nice it sounds to how ugly it looks. Kind of like it had nail varnish spilt on it , then set on fire, and it started out yellow. But Partridge iron, and minimalist preamp make this a really nice, and powerful sounding amp. Replaced a dodge looking cap, and new valves in it. £400

Hiwatt DR103, 1969 so predates Harry Joyce joining and doing all the inking. Clearly a working amp for a long time, various mods, some of which I can return to original, but they are mostly fairly practical ones, like an IEC socket. SOLD

50w 2xEL34 Laney AOR combo, SOLD

Sound City 120, revalved and recapped and some noisy parts replaced. SOLD

100w Hiwatt PA. Sounds fine for bass, one input is missing, so only 5. £550

Laney Supergroup series 200w white face bass amp

A mate just dropped this round for me to look at. Pretty rare, not heard of them before. 200w Supergroup instrument head.

200w supergroup

Inside, its runs from 6 EL34, and massive Partridge iron, with the Laney style both at one end thing which makes it a proper pain in the nuts to carry.


Underneath, same style as the Klipps, but bigger:


Big enough the other board needs a separate pic:


Can’t say how it sounds because opening it shows a few of those big caps aren’t actually soldered at the ends, pretty similar to one of the Klipps. supposedly had been serviced too, which appears to have been putting a new valve in and not even dusting it. Going to need a bit of a going over before I’ll be firing it up, lots of power going on.
