Maplin's administrator has failed to find a buyer for the fallen electricals retailer, triggering further redundancies at the firm.
While the firm remained "open to interest" to find a buyer, administrator PwC said it would have to make another 66 redundancies at Maplin's head offices in London and Rotherham.
It said that 57 roles will go in the capital and nine in South Yorkshire would be affected. This brings the total number of job losses to 129.
Maplin has 217 stores in the UK and Ireland, employs 2,335 staff, and boasts an annual turnover of £235.8m.
It entered administration last month, with PwC laying the blame for its collapse partly at the door of the rising price UK consumers are paying for US-made gadgets.
PwC said it will continue to trade the business as normal while it attempts to find a buyer.
A raft of US tech manufacturers, including HP, Microsoft and Apple, moved to increase their UK prices sharply in the wake of the devaluation of the pound following the June 2016 Brexit referendum.
PwC said Maplin had been the victim of "softening of consumer demand in what has been a challenging retail environment and higher-priced (US denominated) products".
"Given the cash position of the company, the directors resolved to put Maplin into administration," it said.
Zelf Hussain, joint administrator and PwC partner, said at the time of the administration announcement: "The challenging conditions in the UK retail sector are well documented. Like many other retailers, Maplin has been hit hard by a slowdown in consumer spending and more expensive imports as the pound has weakened.
"Our initial focus as administrators will be to engage with parties who may be interested in acquiring all or part of the company. We will continue to trade the business as normal while a buyer is sought.
"Staff have been paid their February wages and will continue to be paid for future work while the company is in administration."
