should be good for 5000 hours.

 

I think they are soldered in.

It is indeed and soldered into the circuit board so it looks like a pig of a job to do if you want to have a crack yourself. Tubes are hard to get as well.

Yes, but that's the only ones I could find too other than £25 plus VAT (plus shipping?) at Watford Valves. I agree that desoldering this tube would be tricky. It's most likely lead free solder (RoHS compliant) which is a pig without higher temperature equipment. If you really want a Markbass head with a valve pre I'd strongly recommend one of the older TA series.

Just had a word with Reel electrics Markbass autherised repairer.£69 plus vat plus tube plus postage.So going to be north of £100. .Expensive tube replacement should you need it.☺

If they are good for 5000 hours perhaps something else is making you think it might be a dodgy tube?

 

Playing amped for 5 hours per week = 260 hours per year = life span of 19 and a bit years.

How old is it?
