Dynacord Bass King T valve head


Recommended Posts

Dynacord Bass King T head, believed to be late 60s/early 70's. This is quite a quirky design with a transistor preamp and valve power stage (much like the old Musicman amps were). Valves are a JJ ECC81 as the phase inverter, and a pair of older "Pinnacle" branded EL34s giving somewhere in the region of 50 watts. Speaker outputs are 16, 8 or 4 ohms. Working nicely, not super loud but provides a sweet old-school bass sound. This amp doesn't get really dirty when cranked, but provides a nice little bit of valvey goodness to your sound! It's relatively small and not too heavy (for a valve amp). Also worth mentioning: the front panel is backlit plexiglass, so it looks great in the dark! It would also be quite a simple matter to rewire one of the input jacks to a power amp input if you wanted to use it with the pre-amp of your choice.
I'm looking for around £80, or would trade for a preamp/DI unit such as a Sansamp or similar, or other interesting item - try me!
Local pickup in Edinburgh is preferred, but I'll look into postage if no-one nearby fancies it.

Hi Umph, I've got to dash out just now, but I'll take a photo of the innards later if I get time...

OK, later:
Here are some pics from above and below with the grilles removed. Here also is a PDF schematic. I'm crazily busy for most of this week - I could probably research postage costs by about Thursday, and post on Saturday morning. I'm still vaguely toying with the idea of keeping it and re-jigging the preamp...

Im in love with this amp. How loud exactly is not very loud? Would it keep up with a drum kit and a couple of guitars? If the answer is yes, then how much to post it to Dublin? THANKS!

OK, I've no scales in the house and a gig tomorrow, but I'll get it put in a suitable box and plonked on some scales on Thursday so I can work out postage. Stay tuned!
It'll certainly keeps up with drums when I've used it - if your guitarists are cranking big amps it might struggle a bit. I think the preamp is quite low-gain, so it can seem less loud than some 50 watt valve amps when used at low settings, but the maximum cleanish volume is about the same as other 2xEL34 amps. With any lower powered valve amp, sensitive speakers are a big help. It's great with an old fashioned 1x15, and slightly underwhelming with my 1x10". Nice sound though, warm and wholesome rather than agressive.

Would love it if I had the money - I'll see if I can get some extra work!

Bump for a lush looking amp![/quote]

Excellent.[/quote]

Nah - gain only would be proper minimalist :rolleyes:

Looks like a really funky piece of kit I must admit!

If it helps APC Couriers (they ship all the basses I make) have a road service to Ireland that is inexpensive. They shipped a bass from me to Dublin and 2 x Technics 1210s

Not gone gone yet, but pending the usual...[/quote]

This arrived last week all in great working order and well packed. Martin is a pleasure to do business with! I'm very happy with the amp. Used it for band practice last night, it sounds very sweet. Got that tubey detailed sound I like. Not terribly loud with one 102HF markbass cab, but I still have to try it with my second cab at 4 ohms.... should make it push a bit more air ( I know these amps don't technically get any louder when the Ohmage is reduced, but more speakers tend to sound bigger). Great wee practice amp and looks absolutely very very totally cool with the backlight behind the perspex panel!

Bugger.....

I actually got some extra work too - enough to cover the cost of buying this amp!

I'm gutted.... can I have 1sts on it if you ever want to sell it sir?

Hi Jesse, glad you're liking the sound. I found running it with the bass and treble controls up a bit (about 2-3 oclock) gives you a little more oomph.
Ben, have you noticed the one on [url="http://cgi.ebay.co.uk/Dynacord-Bass-King-T-Valve-Amp-1970s-FULL-WORKING-ORDER_W0QQitemZ330329578945QQcmdZViewItemQQptZUK_MusicalInstr_Amplifiers_RL?hash=item4ce92d5dc1&_trksid=p3286.c0.m14&_trkparms=72%3A1688|66%3A2|65%3A12|39%3A1|240%3A1318|301%3A0|293%3A1|294%3A50"]ebay[/url]? It's been sitting for weeks, priced a bit high at £250. Since it's not shifting at that price, I'd think they might accept an offer. It's worth a try...

Ben, I'll give you first dibs on it if I decide to sell it... but I don't see that happening for quite a while.... I think its a keeper!
